High Severity 7-zip Vulnerability Allows for Remote Code Execution
A high-severity 7-zip vulnerability, CVE-2025-0411 (CVSS 7/10), was released over the weekend. The vulnerability allows an attacker to bypass the Windows Mark of the Web Security feature, which is designed to identify files downloaded from unverified sources and flag them to restrict execution. By bypassing this feature, users would not be warned that a file extracted from 7-zip is malicious, and an attacker would be able to remotely execute code on the user's device.
Affected Versions
- 7-zip versions before 24.09.

SimpleHelp Remote Access Vulnerabilities Can Lead to Privilege Escalation
SimpleHelp is a remote support software that allows an IT staff to remotely access user workstations without the user's interactions. The most critical vulnerability CVE-2024-57726 (CVSS 9.9/10), allows an attacker with technician access to elevate themselves to an admin role. These attackers can then interact with user machines if unattended access is configured. Two other high-severity vulnerabilities were also fixed in the released patch, CVE-2024-57727 (CVSS 7.5/10) and CVE-2024-57728 (CVSS 7.2/10).

Recommendations
Please review your environment to ensure the above-mentioned issues are patched in a timely manner. It is security best practice to regularly update and/or patch software to the latest versions. The vulnerabilities above highlight the security benefits of limiting deployed software to "vendor-supported versions" only. This dramatically increases the likelihood that new vulnerabilities have a patch issued for them. Likewise, Cybersafe strongly encourages maintaining an inventory of current software in your environment, which helps ensure and inform your patch and vulnerability management program.
