Bot Framework SDK Information Disclosure Vulnerability

Microsoft Internet Explorer before 8 uses the HTTP Host header to determine the context of a document provided in a (1) 4xx or (2) 5xx CONNECT response from a proxy server, which allows man-in-the-middle attackers to execute arbitrary web script by modifying this CONNECT response, aka an "SSL tampering" attack.

The Internet Authentication Service (IAS) in Microsoft Windows Vista SP2 and Server 2008 SP2 does not properly validate MS-CHAP v2 Protected Extensible Authentication Protocol (PEAP) authentication requests, which allows remote attackers to execute arbitrary code via crafted structures in a malformed request, aka "Internet Authentication Service Memory Corruption Vulnerability."

Microsoft Internet Explorer 8, and possibly other versions, detects http content in https web pages only when the top-level frame uses https, which allows man-in-the-middle attackers to execute arbitrary web script, in an https site's context, by modifying an http page to include an https iframe that references a script file on an http site, related to "HTTP-Intended-but-HTTPS-Loadable (HPIHSL) pages."

A vulnerability in Trend Micro Apex One may allow a local attacker to manipulate the process of the security agent unload option (if configured), which then could be manipulated to gain a privilege escalation and code execution. An attacker must first obtain the ability to execute low-privileged code on the target in order to exploit this vulnerability.

Windows Defender Remote Credential Guard Elevation of Privilege Vulnerability

The Secure Channel (aka SChannel) authentication component in Microsoft Windows 2000 SP4, XP SP2 and SP3, Server 2003 SP1 and SP2, Vista Gold and SP1, and Server 2008, when certificate authentication is used, does not properly validate the client's key exchange data in Transport Layer Security (TLS) handshake messages, which allows remote attackers to spoof authentication by crafting a TLS packet based on knowledge of the certificate but not the private key, aka "SChannel Spoofing Vulnerability."

Remote code execution vulnerability due to insufficient user privilege verification in reverseWall-MDS. Remote attackers can exploit the vulnerability such as stealing account, through remote code execution.

IBM Cognos Controller 10.4.0, 10.4.1, and 10.4.2 could allow a remote attacker to bypass security restrictions, caused by improper validation of authentication cookies. IBM X-Force ID: 190847.

Microsoft Office SharePoint Server 2007 Gold and SP1 and Microsoft Search Server 2008 do not properly perform authentication and authorization for administrative functions, which allows remote attackers to cause a denial of service (server load), obtain sensitive information, and "create scripts that would run in the context of the site" via requests to administrative URIs, aka "Access Control Vulnerability."

Microsoft Windows 2000 Gold through SP4, XP Gold through SP3, Server 2003 SP1 and SP2, Vista Gold and SP1, and Server 2008 allows remote SMB servers to execute arbitrary code on a client machine by replaying the NTLM credentials of a client user, as demonstrated by backrush, aka "SMB Credential Reflection Vulnerability." NOTE: some reliable sources report that this vulnerability exists because of an insufficient fix for CVE-2000-0834.

IBM Spectrum Protect Operations Center 8.1.0.000 through 8.1.10.and 7.1.0.000 through 7.1.11 could allow a remote attacker to obtain sensitive information, caused by improper authentication of a websocket endpoint. By using known tools to subscribe to the websocket event stream, an attacker could exploit this vulnerability to obtain sensitive information. IBM X-Force ID: 188993.

vRealize Operations for Horizon Adapter (6.7.x prior to 6.7.1 and 6.6.x prior to 6.6.1) has an improper trust store configuration leading to authentication bypass. An unauthenticated remote attacker who has network access to vRealize Operations, with the Horizon Adapter running, may be able to bypass Adapter authentication.

Adobe FrameMaker Publishing Server versions 2022.1 and earlier are affected by an Improper Authentication vulnerability that could result in a Security feature bypass. An attacker could leverage this vulnerability to bypass authentication mechanisms and gain unauthorized access. Exploitation of this issue does not require user interaction.

Microsoft Internet Explorer before 8 displays a cached certificate for a (1) 4xx or (2) 5xx CONNECT response page returned by a proxy server, which allows man-in-the-middle attackers to spoof an arbitrary https site by letting a browser obtain a valid certificate from this site during one request, and then sending the browser a crafted 502 response page upon a subsequent request.

Improper authentication in Windows NTLM allows an authorized attacker to elevate privileges over a network.

Improper authentication in Azure Stack allows an unauthorized attacker to disclose information over a network.

Improper authentication in Microsoft Office SharePoint allows an unauthorized attacker to perform spoofing over a network.

If LDAP authentication is enabled, an LDAP authentication bypass vulnerability in Trend Micro Vulnerability Protection 2.0 SP2 could allow an unauthenticated attacker with prior knowledge of the targeted organization to bypass manager authentication. Enabling multi-factor authentication prevents this attack. Installations using manager native authentication or SAML authentication are not impacted by this vulnerability.

If LDAP authentication is enabled, an LDAP authentication bypass vulnerability in Trend Micro Deep Security 10.x-12.x could allow an unauthenticated attacker with prior knowledge of the targeted organization to bypass manager authentication. Enabling multi-factor authentication prevents this attack. Installations using manager native authentication or SAML authentication are not impacted by this vulnerability.

On April 18th 2025, Microsoft announced Exchange Server Security Changes for Hybrid Deployments and accompanying non-security Hot Fix. Microsoft made these changes in the general interest of improving the security of hybrid Exchange deployments. Following further investigation, Microsoft identified specific security implications tied to the guidance and configuration steps outlined in the April announcement. Microsoft is issuing CVE-2025-53786 to document a vulnerability that is addressed by taking the steps documented with the April 18th announcement. Microsoft strongly recommends reading the information, installing the April 2025 (or later) Hot Fix and implementing the changes in your Exchange Server and hybrid environment.

The OneClickSigninBubbleView::WindowClosing function in browser/ui/views/sync/one_click_signin_bubble_view.cc in Google Chrome before 32.0.1700.76 on Windows and before 32.0.1700.77 on Mac OS X and Linux allows attackers to trigger a sync with an arbitrary Google account by leveraging improper handling of the closing of an untrusted signin confirm dialog.
