CVE-2025-23172
Published: 19 June 2025
Summary
CVE-2025-23172 is a high-severity SSRF (CWE-918) vulnerability in Versa Networks (inferred from references). Its CVSS base score is 7.2 (High).
Operationally, ranked in the top 21.6% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
The vulnerability affects the Versa Director SD-WAN orchestration platform and stems from insufficient validation in its Webhook feature. Specifically, the Add Webhook and Test Webhook functions permit an authenticated user to submit crafted HTTP requests that target localhost, enabling server-side request forgery (SSRF) under CWE-918.
An attacker with a valid account on the Director GUI can leverage this flaw to issue requests that execute commands as the versa user, who possesses sudo privileges. Successful exploitation can therefore result in privilege escalation or remote code execution on the orchestration platform.
Vendor advisories state there are no workarounds to disable the affected GUI options and recommend upgrading Director to one of the remediated releases listed in the security bulletin and associated software notes. No real-world exploitation has been reported, although third-party researchers have published proof-of-concept code; the EPSS score has remained flat at 0.0110 since disclosure.
