The nsDocShell::OnRedirectStateChange function in docshell/base/nsDocShell.cpp in Mozilla Firefox 3.5.x before 3.5.11 and 3.6.x before 3.6.7, and SeaMonkey before 2.0.6, allows remote attackers to spoof the SSL security status of a document via vectors involving multiple requests, a redirect, and the history.back and history.forward JavaScript functions.

Cross-domain vulnerability in js/src/jsobj.cpp in Mozilla Firefox 3.x before 3.0.6 allows remote attackers to bypass the Same Origin Policy, and access the properties of an arbitrary window and conduct cross-site scripting (XSS) attacks, via vectors involving a chrome XBL method and the window.eval function.

Cross-site scripting (XSS) vulnerability in showdependencygraph.cgi in Bugzilla 2.x, 3.x, and 4.x before 4.2.16, 4.3.x and 4.4.x before 4.4.11, and 4.5.x and 5.0.x before 5.0.2, when a local dot configuration is used, allows remote attackers to inject arbitrary web script or HTML via a crafted bug summary.

A vulnerability was found in Translator PoqDev Add-On 1.0.11 on Firefox. It has been rated as problematic. This issue affects some unknown processing of the component Select Text Handler. The manipulation leads to cross site scripting. The attack may be initiated remotely. The complexity of an attack is rather high. The exploitation is known to be difficult. The exploit has been disclosed to the public and may be used. The identifier VDB-241649 was assigned to this vulnerability. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.

Mozilla Firefox before 41.0, when reader mode is enabled, allows remote attackers to spoof the relationship between address-bar URLs and web content via a crafted web site.

When network partitioning was enabled, e.g. as a result of Enhanced Tracking Protection settings, a TLS error page would allow the user to override an error on a domain which had specified HTTP Strict Transport Security (which implies that the error should not be override-able.) This issue did not affect the network connections, and they were correctly upgraded to HTTPS automatically. This vulnerability affects Firefox < 90.

The session-restore feature in Mozilla Firefox before 28.0 and SeaMonkey before 2.25 does not consider the Content Security Policy of a data: URL, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via a crafted document that is accessed after a browser restart.

Cross-site scripting (XSS) vulnerability in Mozilla Firefox before 2.0, when UTF-7 document content is rendered directly in UTF-7, allows remote attackers to inject arbitrary web script or HTML via a gopher URI that uses single quote characters to delimit a literal string within an XSS sequence, a related issue to CVE-2007-5415.

Cross-site request forgery (CSRF) vulnerability in editversions.cgi in Bugzilla before 2.22.1 and 2.23.x before 2.23.3 allows user-assisted remote attackers to create, modify, or delete arbitrary bug reports via a crafted URL.

Mozilla Thunderbird before 1.5.0.7 and SeaMonkey before 1.0.5, with "Load Images" enabled, allows remote user-assisted attackers to bypass settings that disable JavaScript via a remote XBL file in a message that is loaded when the user views, forwards, or replies to the original message.

Mozilla Firefox before 1.5.0.7 and Thunderbird before 1.5.0.7 makes it easy for users to accept self-signed certificates for the auto-update mechanism, which might allow remote user-assisted attackers to use DNS spoofing to trick users into visiting a malicious site and accepting a malicious certificate for the Mozilla update site, which can then be used to install arbitrary code on the next update.

The popup blocker in Mozilla Firefox before 1.5.0.7 opens the "blocked popups" display in the context of the Location bar instead of the subframe from which the popup originated, which might make it easier for remote user-assisted attackers to conduct cross-site scripting (XSS) attacks.

Mozilla Firefox before 1.5.0.5, Thunderbird before 1.5.0.5, and SeaMonkey before 1.0.3 allows remote attackers to reference remote files and possibly load chrome: URLs by tricking the user into copying or dragging links.

HTTP response smuggling vulnerability in Mozilla Firefox and Thunderbird before 1.5.0.4, when used with certain proxy servers, allows remote attackers to cause Firefox to interpret certain responses as if they were responses from two different sites via (1) invalid HTTP response headers with spaces between the header name and the colon, which might not be ignored in some cases, or (2) HTTP 1.1 headers through an HTTP 1.0 proxy, which are ignored by the proxy but processed by the client.

Mozilla Firefox 1.x before 1.5 and 1.0.x before 1.0.8, Mozilla Suite before 1.7.13, and SeaMonkey before 1.0 allows remote attackers to spoof secure site indicators such as the locked icon by opening the trusted site in a popup window, then changing the location to a malicious site.

Mozilla Firefox 1.x before 1.5 and 1.0.x before 1.0.8, Mozilla Suite before 1.7.13, and SeaMonkey before 1.0 allows remote attackers to trick users into downloading and saving an executable file via an image that is overlaid by a transparent image link that points to the executable, which causes the executable to be saved when the user clicks the "Save image as..." option. NOTE: this attack is made easier due to a GUI truncation issue that prevents the user from seeing the malicious extension when there is extra whitespace in the filename.

Mozilla Firefox 1.5 before 1.5.0.2 and SeaMonkey before 1.0.1 causes certain windows to become translucent due to an interaction between XUL content windows and the history mechanism, which might allow user-assisted remote attackers to trick users into executing arbitrary code.

Mozilla Thunderbird 1.0 and Firefox 1.0.6 allows remote attackers to obfuscate URIs via a long URI, which causes the address bar to go blank and could facilitate phishing attacks.

Firefox before 1.0.5 and Mozilla before 1.7.9 does not clearly associate a Javascript dialog box with the web page that generated it, which allows remote attackers to spoof a dialog box from a trusted site and facilitates phishing attacks, aka the "Dialog Origin Spoofing Vulnerability."

A regression error in Firefox 1.0.3 and Mozilla 1.7.7 allows remote attackers to inject arbitrary Javascript from one page into the frameset of another site, aka the frame injection spoofing vulnerability, a re-introduction of a vulnerability that was originally identified and addressed by CVE-2004-0718.

The file download dialog in Mozilla Firefox 0.10.1 and 1.0 for Windows uses the Content-Type HTTP header to determine the file type, but saves the original file extension when "Save to Disk" is selected, which allows remote attackers to hide the real file types of downloaded files.

Firefox before 1.0.2 allows remote attackers to execute arbitrary code by tricking a user into saving a page as a Firefox sidebar panel, then using the sidebar panel to inject Javascript into a privileged page.

Firefox before 1.0.1 and Mozilla before 1.7.6 truncates long sub-domains or paths for display, which may allow remote malicious web sites to spoof legitimate sites and facilitate phishing attacks.

Firefox before 1.0.1 and Mozilla before 1.7.6 allows remote malicious web sites to overwrite arbitrary files by tricking the user into downloading a .LNK (link) file twice, which overwrites the file that was referenced in the first .LNK file.

Firefox before 1.0.1 and Mozilla before 1.7.6 allows remote attackers to spoof the SSL "secure site" lock icon via (1) a web site that does not finish loading, which shows the lock of the previous site, (2) a non-HTTP server that uses SSL, which causes the lock to be displayed when the SSL handshake is completed, or (3) a URL that generates an HTTP 204 error, which updates the icon and location information but does not change the display of the original site.

Firefox before 1.0 does not properly distinguish between user-generated and synthetic click events, which allows remote attackers to use Javascript to bypass the file download prompt when the user uses the Alt-click feature.

Firefox 1.0 does not invoke the Javascript Security Manager when a user drags a javascript: or data: URL to a tab, which allows remote attackers to bypass the security model, aka "firetabbing."

Firefox before 1.0 and Mozilla before 1.7.5 display the SSL lock icon when an insecure page loads a binary file from a trusted site, which could facilitate phishing attacks.

Firefox 1.0 allows remote attackers to modify Boolean configuration parameters for the about:config site by using a plugin such as Flash, and the -moz-opacity filter, to display the about:config site then cause the user to double-click at a certain screen position, aka "Fireflashing."

Mozilla before 1.6 does not display the entire URL in the status bar when a link contains %00, which could allow remote attackers to trick users into clicking on unknown or untrusted sites and facilitate phishing attacks.

The Apple Java plugin, as used in Netscape 7.1 and 7.2, Mozilla 1.7.2, and Firefox 0.9.3 on MacOS X 10.3.5, when tabbed browsing is enabled, does not properly handle SetWindow(NULL) calls, which allows Java applets from one tab to draw to other tabs and facilitates phishing attacks that spoof tabs.

Sun Java Runtime Environment (JRE) in JDK and JRE 6 Update 2 and earlier, JDK and JRE 5.0 Update 12 and earlier, SDK and JRE 1.4.2_15 and earlier, and SDK and JRE 1.3.1_20 and earlier, when Firefox or Opera is used, allows remote attackers to violate the security model for JavaScript outbound connections via a multi-pin DNS rebinding attack dependent on the LiveConnect API, in which JavaScript download relies on DNS resolution by the browser, but JavaScript socket operations rely on separate DNS resolution by a Java Virtual Machine (JVM), a different issue than CVE-2007-5273. NOTE: this is similar to CVE-2007-5232.

Mozilla Firefox 4.x through 11.0, Thunderbird 5.0 through 11.0, and SeaMonkey before 2.9 do not properly construct the Origin and Sec-WebSocket-Origin HTTP headers, which might allow remote attackers to bypass an IPv6 literal ACL via a cross-site (1) XMLHttpRequest or (2) WebSocket operation involving a nonstandard port number and an IPv6 address that contains certain zero fields.

Firefox before 1.0.1 and Mozilla before 1.7.6, when displaying the HTTP Authentication dialog, do not change the focus to the tab that generated the prompt, which could facilitate spoofing and phishing attacks.

Firefox before 1.0.1 and Mozilla before 1.7.6 allows remote malicious web sites to spoof the extensions of files to download via the Content-Disposition header, which could be used to trick users into downloading dangerous content.

Firefox before 1.0.1 allows remote attackers to spoof the (1) security and (2) download modal dialog boxes, which could be used to trick users into executing script or downloading and executing a file, aka "Firespoofing."

Mozilla Firefox before 36.0 does not properly restrict transitions of JavaScript objects from a non-extensible state to an extensible state, which allows remote attackers to bypass a Caja Compiler sandbox protection mechanism or a Secure EcmaScript sandbox protection mechanism via a crafted web site.

Firefox before 1.0 and Mozilla before 1.7.5 display the secure site lock icon when a view-source: URL references a secure SSL site while an insecure page is being loaded, which could facilitate phishing attacks.

The normalizeDocument function in Mozilla Firefox before 3.5.12 and 3.6.x before 3.6.9, Thunderbird before 3.0.7 and 3.1.x before 3.1.3, and SeaMonkey before 2.0.7 does not properly handle the removal of DOM nodes during normalization, which might allow remote attackers to execute arbitrary code via vectors involving access to a deleted object.

Insufficient escaping in the “Copy as cURL” feature could potentially be used to trick a user into executing unexpected code. This vulnerability affects Firefox < 141, Firefox ESR < 128.13, Firefox ESR < 140.1, Thunderbird < 141, Thunderbird < 128.13, and Thunderbird < 140.1.

Mozilla Firefox 4.x through 7.0 and Thunderbird 5.0 through 7.0 perform access control without checking for use of the NoWaiverWrapper wrapper, which allows remote attackers to gain privileges via a crafted web site.

CRLF injection vulnerability in Bugzilla 2.17.1 through 2.22.7, 3.0.x through 3.3.x, 3.4.x before 3.4.12, 3.5.x, 3.6.x before 3.6.6, 3.7.x, 4.0.x before 4.0.2, and 4.1.x before 4.1.3 allows remote attackers to inject arbitrary e-mail headers via an attachment description in a flagmail notification.

Mozilla Firefox 3.6.x before 3.6.3 does not properly manage the scopes of DOM nodes that are moved from one document to another, which allows remote attackers to conduct use-after-free attacks and execute arbitrary code via unspecified vectors involving improper interaction with garbage collection, as demonstrated by Nils during a Pwn2Own competition at CanSecWest 2010.

Mozilla Firefox 3.6.x before 3.6.7 and Thunderbird 3.1.x before 3.1.1 do not properly implement access to a content object through a SafeJSObjectWrapper (aka SJOW) wrapper, which allows remote attackers to execute arbitrary JavaScript code with chrome privileges by leveraging "access to an object from the chrome scope."

Mozilla Firefox before 3.0.19 and 3.5.x before 3.5.8, and SeaMonkey before 2.0.3, when the XMLHttpRequestSpy module in the Firebug add-on is used, does not properly handle interaction between the XMLHttpRequestSpy object and chrome privileged objects, which allows remote attackers to execute arbitrary JavaScript via a crafted HTTP response.

Mozilla Firefox before 3.0.19, 3.5.x before 3.5.9, and 3.6.x before 3.6.2, and SeaMonkey before 2.0.4, does not prevent applets from interpreting mouse clicks as drag-and-drop actions, which allows remote attackers to execute arbitrary JavaScript with Chrome privileges by loading a chrome: URL and then loading a javascript: URL.
