CVE-2014-9905 Alinto CVE debrief

Who should care

Administrators and security teams running SOGo Web Calendar, especially where users can create or view shared appointments and contacts.

Technical summary

The vulnerability is categorized as CWE-79 (XSS). The attack surface is the web calendar interface: untrusted content in appointment titles or contact fields can be rendered in a browser and execute in the context of the application. NVD lists the affected CPE range as SOGo up to 2.1.1, while the CVE description states before 2.2.0; both indicate older releases are affected.

Defensive priority

Medium. The issue requires user interaction, but it can affect browser sessions and integrity of rendered content in a collaboration product used by multiple users.

Recommended defensive actions

• Upgrade SOGo to a version at or beyond the fixed release referenced by the CVE description (2.2.0 or later).
• Review the vendor advisory and related patch commits for the exact remediation applied to calendar and contact rendering.
• Verify that calendar titles and contact fields are consistently output-encoded and sanitized before browser rendering.
• Search for existing malicious or unexpected HTML/script content in stored calendar entries and contacts, then remove or neutralize it.
• Apply defense-in-depth controls such as restrictive content security policies where practical.
