An issue was discovered in Open Ticket Request System (OTRS) 7.0.x through 7.0.8, and Community Edition 5.0.x through 5.0.36 and 6.0.x through 6.0.19. An attacker who is logged into OTRS as an agent user with appropriate permissions can leverage OTRS notification tags in templates in order to disclose hashed user passwords.

In trytond/model/modelstorage.py in Tryton 4.2 before 4.2.21, 4.4 before 4.4.19, 4.6 before 4.6.14, 4.8 before 4.8.10, and 5.0 before 5.0.6, an authenticated user can order records based on a field for which he has no access right. This may allow the user to guess values.

MediaWiki through 1.32.1 has Incorrect Access Control. Suppressed username or log in Special:EditTags are exposed. Fixed in 1.32.2, 1.31.2, 1.30.2 and 1.27.6.

Wikimedia MediaWiki through 1.32.1 has Incorrect Access Control. Suppressed log in RevisionDelete page is exposed. Fixed in 1.32.2, 1.31.2, 1.30.2 and 1.27.6.

ansible-playbook -k and ansible cli tools, all versions 2.8.x before 2.8.4, all 2.7.x before 2.7.13 and all 2.6.x before 2.6.19, prompt passwords by expanding them from templates as they could contain special characters. Passwords should be wrapped to prevent templates trigger and exposing them.

Directory traversal vulnerability in RequestUtil.java in Apache Tomcat 6.x before 6.0.45, 7.x before 7.0.65, and 8.x before 8.0.27 allows remote authenticated users to bypass intended SecurityManager restrictions and list a parent directory via a /.. (slash dot dot) in a pathname used by a web application in a getResource, getResourceAsStream, or getResourcePaths call, as demonstrated by the $CATALINA_BASE/webapps directory.

Unspecified vulnerability in Oracle MySQL Server 5.5.45 and earlier and 5.6.26 and earlier allows remote authenticated users to affect confidentiality via unknown vectors related to Server : Types.

The Render cache system in Drupal 7.x before 7.38, when used to cache content by user role, allows remote authenticated users to obtain private content viewed by user 1 by reading the cache.

slirp.c in libslirp through 4.3.1 has a buffer over-read because it tries to read a certain amount of header data even if that exceeds the total packet length.

Guzzle, an extensible PHP HTTP client. `Authorization` and `Cookie` headers on requests are sensitive information. In affected versions on making a request which responds with a redirect to a URI with a different port, if we choose to follow it, we should remove the `Authorization` and `Cookie` headers from the request, before containing. Previously, we would only consider a change in host or scheme. Affected Guzzle 7 users should upgrade to Guzzle 7.4.5 as soon as possible. Affected users using any earlier series of Guzzle should upgrade to Guzzle 6.5.8 or 7.4.5. Note that a partial fix was implemented in Guzzle 7.4.2, where a change in host would trigger removal of the curl-added Authorization header, however this earlier fix did not cover change in scheme or change in port. An alternative approach would be to use your own redirect middleware, rather than ours, if you are unable to upgrade. If you do not require or expect redirects to be followed, one should simply disable redirects all together.

Nokogiri is a Rubygem providing HTML, XML, SAX, and Reader parsers with XPath and CSS selector support. In Nokogiri before version 1.11.0.rc4 there is an XXE vulnerability. XML Schemas parsed by Nokogiri::XML::Schema are trusted by default, allowing external resources to be accessed over the network, potentially enabling XXE or SSRF attacks. This behavior is counter to the security policy followed by Nokogiri maintainers, which is to treat all input as untrusted by default whenever possible. This is fixed in Nokogiri version 1.11.0.rc4.

In Mosquitto before 1.4.12, pattern based ACLs can be bypassed by clients that set their username/client id to '#' or '+'. This allows locally or remotely connected clients to access MQTT topics that they do have the rights to. The same issue may be present in third party authentication/access control plugins for Mosquitto.

If an HTTP/2 client connecting to Apache Tomcat 10.0.0-M1 to 10.0.0-M7, 9.0.0.M1 to 9.0.37 or 8.5.0 to 8.5.57 exceeded the agreed maximum number of concurrent streams for a connection (in violation of the HTTP/2 protocol), it was possible that a subsequent request made on that connection could contain HTTP headers - including HTTP/2 pseudo headers - from a previous request rather than the intended headers. This could lead to users seeing responses for unexpected resources.

The dump_resource function in dird/dird_conf.c in Bacula before 5.2.11 does not properly enforce ACL rules, which allows remote authenticated users to obtain resource dump information via unspecified vectors.

In the Agent Frontend in Open Ticket Request System (OTRS) 3.3.x through 3.3.18, with a crafted URL it is possible to gain information like database user and password.

It was found that libpam4j up to and including 1.8 did not properly validate user accounts when authenticating. A user with a valid password for a disabled account would be able to bypass security restrictions and possibly access sensitive information.

Gitlab Enterprise Edition version 10.1.0 is vulnerable to an insufficiently protected credential issue in the project service integration API endpoint resulting in an information disclosure of plaintext password.

An issue was discovered in LemonLDAP::NG before 2.0.12. Session cache corruption can lead to authorization bypass or spoofing. By running a loop that makes many authentication attempts, an attacker might alternately be authenticated as one of two different users.

eLabFTW is an open source electronic lab notebook manager for research teams. In versions of eLabFTW before 4.1.0, it allows attackers to bypass a brute-force protection mechanism by using many different forged PHPSESSID values in HTTP Cookie header. This issue has been addressed by implementing brute force login protection, as recommended by Owasp with Device Cookies. This mechanism will not impact users and will effectively thwart any brute-force attempts at guessing passwords. The only correct way to address this is to upgrade to version 4.1.0. Adding rate limitation upstream of the eLabFTW service is of course a valid option, with or without upgrading.

An issue was discovered in Bitrix24 Bitrix Framework (1c site management) 20.0. An "User enumeration and Improper Restriction of Excessive Authentication Attempts" vulnerability exists in the admin login form, allowing a remote user to enumerate users in the administrator group. This also allows brute-force attacks on the passwords of users not in the administrator group.

Nextcloud talk is a chat module for the Nextcloud server platform. In affected versions brute force protection of public talk conversation passwords can be bypassed, as there was an endpoint validating the conversation password without registering bruteforce attempts. It is recommended that the Nextcloud Talk app is upgraded to 15.0.8, 16.0.6 or 17.1.1. There are no known workarounds for this vulnerability.

The login page on D-Link DIR-615 T1 20.10 devices allows remote attackers to bypass the CAPTCHA protection mechanism and conduct brute-force attacks.

An information disclosure vulnerability exists in GitLab CE/EE <v12.3.2, <v12.2.6, and <v12.1.12 that allowed project milestones to be disclosed via groups browsing.

EspoCRM 5.6.4 is vulnerable to user password hash enumeration. A malicious authenticated attacker can brute-force a user password hash by 1 symbol at a time using specially crafted api/v1/User?filterList filters.

In cPanel before 90.0.17, 2FA can be bypassed via a brute-force approach (SEC-575).

Improper Restriction of Excessive Authentication Attempts vulnerability in Digital Operation Services WiFiBurada allows Use of Known Domain Credentials.This issue affects WiFiBurada: before 1.0.5.
