Description
Apache log4net versions before 2.0.10 do not disable XML external entities when parsing log4net configuration files. This allows for XXE-based attacks in applications that accept attacker-controlled log4net configuration files.
Weaknesses (CWE)
- CWE-611 — Improper Restriction of XML External Entity Reference
