Action: Apply mitigations as per vendor instructions and follow applicable BOD 22-01 guidance.

Fortra GoAnywhere MFT Vulnerability

CVE-2025-10035: This vulnerability involves deserialization of untrusted data, allowing execution of arbitrary commands on affected systems.
Action: Users should upgrade to a patched version (latest release 7.8.4).
Additional details can be found in the Fortra Advisory.

Libraesva ESG Vulnerability

CVE-2025-59689: A command injection vulnerability exploited by nation-state actors through specially crafted compressed attachments.
This flaw allows attackers to execute arbitrary commands as a non-privileged user.
Action: Users should upgrade to the latest version of Libraesva ESG.
More information can be found in the Libraesva advisory.

Sudo Vulnerabilities

CVE-2025-32463: This vulnerability allows local users to escalate privileges to root on affected systems.
Action: Users should apply mitigations as per vendor recommendations and follow applicable BOD 22-01 guidance.
Additional details are available in the Sudo security advisory.

Libraesva ESG Zero-Day Exploit

The Libraesva Email Security Gateway (ESG) has been targeted by suspected state-sponsored attackers exploiting a zero-day vulnerability.

CVE-2025-59689 Details

This command injection vulnerability results from improper sanitization of code in compressed archive files.
Attackers can execute arbitrary shell commands using specially crafted emails.
The vulnerability affects versions from 4.5 to 5.5.
Fixes have been rolled out for the 5.x branches via automatic updates.
For 4.x users, a manual upgrade to a fixed 5.x version is required as 4.x is no longer supported.

Response to Exploit

Libraesva has confirmed that their security team is analyzing details of the attack and has rolled out an emergency security update. They emphasize the importance of rapid patch deployment due to the precision of the threat actor believed to be a foreign state.
