CVE-2019-14466 — Gosa Project Gosa security vulnerability

Medium CVSS 6.5

The GOsa_Filter_Settings cookie in GONICUS GOsa 2.7.5.2 is vulnerable to PHP objection injection, which allows a remote authenticated attacker to perform file deletions (in the context of the user account that runs the web server) via a crafted cookie value, because unserialize is used to restore filter settings from a cookie.

Matched remediation archetype

Unsafe deserialization and object reconstruction

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Inventory serialization formats accepted from requests, queues, caches, files, cookies, and cross-service messages.
  • Trace whether untrusted input can select classes, types, callbacks, constructors, or object hooks during decoding.
  • Identify signing, schema validation, trust-boundary, and compatibility settings for each decoder.

Remediate safely

  • Replace native object deserialization with a data-only format and explicit schema validation.
  • If replacement is not immediate, use a safe decoder with a minimal type allowlist and disable polymorphic or executable hooks.
  • Update the affected library and add inert tests for unknown types, extra fields, malformed nesting, and unsigned data.
