Experts Uncover Severe AWS Flaws Leading to RCE, Data Theft, and Full-Service Takeovers

Cybersecurity researchers have discovered multiple critical flaws in Amazon Web Services (AWS) offerings that, if successfully exploited, could result in serious consequences. "The impact of these vulnerabilities range between remote code execution (RCE), full-service user takeover (which might provide powerful administrative access), manipulation of AI modules, exposing sensitive data, data

GHSA-857q-xmph-p2v5: s2n-tls's mTLS API ordering may skip client authentication

### Impact An API ordering issue in s2n-tls can cause client authentication to unexpectedly not be enabled on the server when it otherwise appears to be. Server applications are impacted if client authentication is enabled by calling s2n_connection_set_config() before calling s2n_connection_set_client_auth_type(). Applications are not impacted if these APIs are called in the opposite order, or if client authentication is enabled on the config with s2n_config_set_client_auth_type(). s2n-tls clients verifying server certificates are not impacted. Impacted versions: < v1.5.0. ### Patches The patch is included in v1.5.0 [1]. ### Workarounds Applications can workaround this issue by calling s2n_connection_set_config() after calling s2n_connection_set_client_auth_type(), or by enabling client authentication on the config with s2n_config_set_client_auth_type(). If you have any questions or comments about this advisory we ask that you contact AWS/Amazon Security via our vulnerability...

Ubuntu Security Notice USN-6923-2

Ubuntu Security Notice 6923-2 - Benedict Schlüter, Supraja Sridhara, Andrin Bertschi, and Shweta Shinde discovered that an untrusted hypervisor could inject malicious #VC interrupts and compromise the security guarantees of AMD SEV-SNP. This flaw is known as WeSee. A local attacker in control of the hypervisor could use this to expose sensitive information or possibly execute arbitrary code in the trusted execution environment. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.

The Power and Peril of RMM Tools

As more people work remotely, IT departments must manage devices distributed over different cities and countries relying on VPNs and remote monitoring and management (RMM) tools for system administration.  However, like any new technology, RMM tools can also be used maliciously. Threat actors can establish connections to a victim's device and run commands, exfiltrate data, and stay
