Xerox Versalink printers are vulnerable to pass-back attacks. Rapid7 discovers LDAP & SMB flaws (CVE-2024-12510 & CVE-2024-12511). Update…

Attackers are using patched bugs to potentially gain unfettered access to an organization's Windows environment under certain conditions.

Security vulnerabilities have been disclosed in Xerox VersaLink C7025 Multifunction printers (MFPs) that could allow attackers to capture authentication credentials via pass-back attacks via Lightweight Directory Access Protocol (LDAP) and SMB/FTP services. "This pass-back style attack leverages a vulnerability that allows a malicious actor to alter the MFP's configuration and cause the MFP

Web shops are an attractive target. How can SMBs keep theirs safe?

While Microsoft has boosted the security of Windows Print Spooler in the three years since the disclosure of the PrintNightmare vulnerability, the service remains a spooky threat that organizations cannot afford to ignore.

This Tech Tip outlines what enterprise defenders need to do to protect their enterprise environment from the new NTLM vulnerability.

Introduction In February 2024, we released an update to Exchange Server which contained a security improvement referenced by CVE-2024-21410 that enabled Extended Protection for Authentication (EPA) by default for new and existing installs of Exchange 2019. While we’re currently unaware of any active threat campaigns involving NTLM relaying attacks against Exchange, we have observed threat actors exploiting this vector in the past.

Proposals from Google and Apple drastically reduce the life cycle of certificates, which should mean more oversight — and hopefully better control.

Ubuntu Security Notice 7123-1 - It was discovered that the CIFS network file system implementation in the Linux kernel did not properly validate certain SMB messages, leading to an out-of-bounds read vulnerability. An attacker could use this to cause a denial of service or possibly expose sensitive information. Supraja Sridhara, Benedict Schlüter, Mark Kuhne, Andrin Bertschi, and Shweta Shinde discovered that the Confidential Computing framework in the Linux kernel for x86 platforms did not properly handle 32-bit emulation on TDX and SEV. An attacker with access to the VMM could use this to cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice 7089-7 - Chenyuan Yang discovered that the USB Gadget subsystem in the Linux kernel did not properly check for the device to be enabled before writing. A local attacker could possibly use this to cause a denial of service. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.
