Improper Certificate Validation

The TLS certificate validation code is flawed. An attacker can obtain a TLS certificate from the Stork server and use it to connect to the Stork agent. Once this connection is established with the valid certificate, the attacker can send malicious commands to a monitored service (Kea or BIND 9), possibly resulting in confidential data loss and/or denial of service. It should be noted that this vulnerability is not related to BIND 9 or Kea directly, and only customers using the Stork management tool are potentially affected. This issue affects Stork versions 0.15.0 through 1.15.0.Show less

electron-updater allows for automatic updates for Electron apps. The file `packages/electron-updater/src/windowsExecutableCodeSignatureVerifier.ts` implements the signature validation routine for Electron applications on Windows. Because of the surrounding shell, a first pass by `cmd.exe` expands any environment variable found in command-line above. This creates a situation where `verifySignature()` can be tricked into validating the certificate of a different file than the one that was just downloaded. If the step is successful, the malicious update will be executed even if its signature is invalid. This attack assumes a compromised update manifest (server compromise, Man-in-the-Middle attack if fetched over HTTP, Cross-Site Scripting to point the application to a malicious updater server, etc.). The patch is available starting from 6.3.0-alpha.6.Show less

An improper certificate validation vulnerability [CWE-295] in FortiWeb 7.2.0 through 7.2.1, 7.0 all versions, 6.4 all versions and 6.3 all versions may allow a remote and unauthenticated attacker in a Man-in-the-Middle position to decipher and/or tamper with the communication channel between the device and different endpoints used to fetch data for Web Application Firewall (WAF).Show less

An improper certificate validation vulnerability [CWE-295] in FortiADC 7.4.0, 7.2 all versions, 7.1 all versions, 7.0 all versions may allow a remote and unauthenticated attacker to perform a Man-in-the-Middle attack on the communication channel between the device and public SDN connectors.Show less

An improper certificate validation vulnerability [CWE-295] in FortiADC 7.4.0, 7.2.0 through 7.2.3, 7.1 all versions, 7.0 all versions, 6.2 all versions, 6.1 all versions and 6.0 all versions may allow a remote and unauthenticated attacker to perform a Man-in-the-Middle attack on the communication channel between the device and various remote servers such as private SDN connectors and FortiToken Cloud.Show less

Botan is a C++ cryptography library. X.509 certificates can identify elliptic curves using either an object identifier or using explicit encoding of the parameters. A bug in the parsing of name constraint extensions in X.509 certificates meant that if the extension included both permitted subtrees and excluded subtrees, only the permitted subtree would be checked. If a certificate included a name which was permitted by the permitted subtree but also excluded by excluded subtree, it would be accepted. Fixed in versions 3.5.0 and 2.19.5.Show less

In gnss service, there is a possible escalation of privilege due to improper certificate validation. This could lead to remote escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS08720039; Issue ID: MSV-1424.Show less

IBM Cognos Analytics 11.2.0, 11.2.1, 11.2.2, 11.2.3, 11.2.4, 12.0.0, 12.0.1, and 12.0.2 is vulnerable to improper certificate validation when using the IBM Planning Analytics Data Source Connection. This could allow an attacker to spoof a trusted entity by interfering in the communication path between IBM Planning Analytics server and IBM Cognos Analytics server. IBM X-Force ID: 283364.Show less

Improper Certificate Validation vulnerability in LibreOffice "LibreOfficeKit" mode disables TLS certification verification LibreOfficeKit can be used for accessing LibreOffice functionality through C/C++. Typically this is used by third party components to reuse LibreOffice as a library to convert, view or otherwise interact with documents. LibreOffice internally makes use of "curl" to fetch remote resources such as images hosted on webservers. In affected versions of LibreOffice, when used in LibreOfficeKit mode only, then curl's TLS certification verification was disabled (CURLOPT_SSL_VERIFYPEER of false) In the fixed versions curl operates in LibreOfficeKit mode the same as in standard mode with CURLOPT_SSL_VERIFYPEER of true. This issue affects LibreOffice before version 24.2.4.Show less

A vulnerability exists in the FOXMAN-UN/UNEM server that affects the message queueing mechanism’s certificate validation. If exploited an attacker could spoof a trusted entity causing a loss of confidentiality and integrity.Show less

A privilege escalation vulnerability exists in the Foxit Reader 2024.2.0.25138. The vulnerability occurs due to improper certification validation of the updater executable before executing it. A low privilege user can trigger the update action which can result in unexpected elevation of privilege.Show less

TP-Link Tether versions prior to 4.5.13 and TP-Link Tapo versions prior to 3.3.6 do not properly validate certificates, which may allow a remote unauthenticated attacker to eavesdrop on an encrypted communication via a man-in-the-middle attack.Show less

An issue was discovered on certain Nuki Home Solutions devices. Lack of certificate validation on HTTP communications allows attackers to intercept and tamper data. This affects Nuki Smart Lock 3.0 before 3.3.5, Nuki Bridge v1 before 1.22.0 and Nuki Bridge v2 before 2.13.2.Show less

An improper certificate validation vulnerability exists in BIG-IP Next Central Manager and may allow an attacker to impersonate an Instance Provider system.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.Show less

In TBD of TBD, there is a possible confusion of OEM and DRM certificates due to improperly used crypto. This could lead to local bypass of DRM content protection with no additional execution privileges needed. User interaction is not needed for exploitation.Show less
