A recently disclosed server-side request forgery (SSRF) vulnerability impacting Ivanti Connect Secure and Policy Secure products has come under mass exploitation. The Shadowserver Foundation said it observed exploitation attempts originating from more than 170 unique IP addresses that aim to establish a reverse shell, among others. The attacks exploit CVE-2024-21893 (CVSS

Boundary and Boundary Enterprise (“Boundary”) is vulnerable to session hijacking through TLS certificate tampering. An attacker with privileges to enumerate active or pending sessions, obtain a private key pertaining to a session, and obtain a valid trust on first use (TOFU) token may craft a TLS certificate to hijack an active session and gain access to the underlying service or application.

A flaw was found in m2crypto. This issue may allow a remote attacker to decrypt captured messages in TLS servers that use RSA key exchanges, which may lead to exposure of confidential or sensitive data.

A flaw was found in the python-cryptography package. This issue may allow a remote attacker to decrypt captured messages in TLS servers that use RSA key exchanges, which may lead to exposure of confidential or sensitive data.

Ubuntu Security Notice 6622-1 - David Benjamin discovered that OpenSSL incorrectly handled excessively long X9.42 DH keys. A remote attacker could possibly use this issue to cause OpenSSL to consume resources, leading to a denial of service. Sverker Eriksson discovered that OpenSSL incorrectly handled POLY1304 MAC on the PowerPC architecture. A remote attacker could use this issue to cause OpenSSL to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 22.04 LTS and Ubuntu 23.04.

Gentoo Linux Security Advisory 202402-8 - Multiple vulnerabilities have been found in OpenSSL, the worst of which could result in denial of service. Versions greater than or equal to 3.0.10 are affected.

Red Hat has always been an advocate of growth at the intersection of open source and computing solutions–which is exactly where RISC-V can be found. RISC-V is one of those technologies where the future is both evident and inevitable. By integrating open source concepts with the hardware development process, it’s not hyperbole to say that RISC-V is disrupting the hardware industry.Our excitement around the unique value RISC-V brings to the hardware ecosystem as an open and collaborative instruction set architecture (ISA) is nothing new. Red Hat has been providing Fedora on RISC-V for severa

### Vulnerability type Cryptography ### Workarounds Refer to the [gateway documentation](https://github.com/etcd-io/etcd/blob/master/Documentation/op-guide/gateway.md). The vulnerability was spotted due to unclear documentation of how the gateway handles endpoints validation. ### Detail Secure endpoint validation is performed by the etcd gateway start command when the --discovery-srv flag is enabled. However, as currently implemented, it only validates TCP reachability, effectively allowing connections to an endpoint that doesn't accept TLS connections through the HTTPS URL. The auditors has noted that appropriate documentation of this validation functionality plus deprecation of this misleading functionality is an acceptable path forward. ### References Find out more on this vulnerability in the [security audit report](https://github.com/etcd-io/etcd/blob/master/security/SECURITY_AUDIT.pdf) ### For more information If you have any questions or comments about this advisory: * Cont...

### Vulnerability type Cryptography ### Detail The TLS ciphers list supported by etcd by default contains weak ciphers. ### Workarounds Provide a desired ciphers using the `--cipher-suites` flag as described with examples in the [security documentation](https://github.com/etcd-io/etcd/blob/master/Documentation/op-guide/security.md) ### References Find out more on this vulnerability in the [security audit report](https://github.com/etcd-io/etcd/blob/master/security/SECURITY_AUDIT.pdf) ### For more information If you have any questions or comments about this advisory: * Contact the [etcd security committee](https://github.com/etcd-io/etcd/blob/master/security/security-release-process.md#product-security-committee-psc)

This Metasploit module exploits a vulnerability in Fortra GoAnywhere MFT that allows an unauthenticated attacker to create a new administrator account. This can be leveraged to upload a JSP payload and achieve RCE. GoAnywhere MFT versions 6.x from 6.0.1, and 7.x before 7.4.1 are vulnerable.
