An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client. If a TLSv1.2 renegotiation ClientHello omits the signature_algorithms extension (where it was present in the initial ClientHello), but includes a signature_algorithms_cert extension then a NULL pointer dereference will result, leading to a crash and a denial of service attack. A server is only vulnerable if it has TLSv1.2 and renegotiation enabled (which is the default configuration). OpenSSL TLS clients are not impacted by this issue. All OpenSSL 1.1.1 versions are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1k. OpenSSL 1.0.2 is not impacted by this issue. Fixed in OpenSSL 1.1.1k (Affected 1.1.1-1.1.1j).

The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023.

The Dell Secure Connect Gateway (SCG) Application and Appliance, versions prior to 5.28, contains a SQL injection vulnerability due to improper neutralization of special elements used in an SQL command. This vulnerability can only be exploited locally on the affected system. A high-privilege attacker with access to the system could potentially exploit this vulnerability, leading to the disclosure of non-sensitive information that does not include any customer data.

In Splunk Enterprise versions below 9.3.2, 9.2.4, and 9.1.7, and versions below 3.4.261 and 3.7.13 of the Splunk Secure Gateway app on Splunk Cloud Platform, a low-privileged user that does not hold the “admin“ or “power“ Splunk roles could perform a Remote Code Execution (RCE).

In Splunk Enterprise versions below 9.3.2, 9.2.4, and 9.1.7 and versions below 3.2.462, 3.7.18, and 3.8.5 of the Splunk Secure Gateway app on Splunk Cloud Platform, a low-privileged user that does not hold the “admin“ or “power“ Splunk roles could see alert search query responses using Splunk Secure Gateway App Key Value Store (KVstore) collections endpoints due to improper access control.

Dell Secure Connect Gateway (SCG) 5.0 Appliance - SRS, version(s) 5.24, contains a Use of a Broken or Risky Cryptographic Algorithm vulnerability. A low privileged attacker with remote access could potentially exploit this vulnerability, leading to information disclosure. The attacker may be able to use exposed credentials to access the system with privileges of the compromised account.

Dell Secure Connect Gateway (SCG) 5.0 Appliance - SRS, version(s) 5.24, contains an Improper Certificate Validation vulnerability. A low privileged attacker with remote access could potentially exploit this vulnerability, leading to unauthorized access and modification of transmitted data.

Dell Secure Connect Gateway (SCG) 5.24 contains an Incorrect Default Permissions vulnerability. A local attacker with low privileges can access the file system and could potentially exploit this vulnerability to gain write access to unauthorized data and cause a version update failure condition.

The Freemius SDK, as used by hundreds of WordPress plugin and theme developers, was vulnerable to Cross-Site Request Forgery and Information disclosure due to missing capability checks and nonce protection on the _get_debug_log, _get_db_option, and the _set_db_option functions in versions up to, and including 2.4.2. Any WordPress plugin or theme running a version of Freemius less than 2.4.3 is vulnerable.

Secure Email Gateway from Cellopoint has Buffer Overflow Vulnerability in authentication process. Remote unauthenticated attackers can send crafted packets to crash the process, thereby bypassing authentication and obtaining system administrator privileges.
