A Server-Side Request Forgery (SSRF) security vulnerability was recently discovered in Zimbra Collaboration Suite, raising security concerns and prompting administrators to promptly apply security patches to affected systems.
According to Zimbra’s latest advisory, this critical SSRF vulnerability affects Zimbra versions 10.1.5 through 10.1.11. Attackers could exploit the issue by manipulating URL requests to trick the server into performing unwanted actions, such as accessing restricted endpoints or internal systems.
The issue, detected in the chat proxy settings module, could allow attackers to gain unauthorized access to internal resources and sensitive user data. While the likelihood of the issue spreading is considered low, its security severity is considered high due to potential data exposure and privilege abuse.
This vector could allow attackers to retrieve configuration files, tokens, or other sensitive data stored in connected services, posing a significant privacy risk to enterprise users who rely on Zimbra for email and collaboration.
Zimbra has released version 10.1.12, which fixes the SSRF flaw and introduces several performance stability updates. Security teams should also verify system integrity after installing the patch and monitor access logs for any suspicious or unauthorized internal requests that could indicate a previous compromise.
Applying the latest update not only mitigates the SSRF threat but also improves Zimbra’s overall resilience and performance. Regular patch maintenance, combined with appropriate configuration hardening, remains the best defense against the ever-evolving threat vectors targeting enterprise collaboration platforms.
