Exploitation vector: Network

Exploit availability: No

Vulnerable software:
Apache Roller
Server applications / Application servers

Vendor: Apache Foundation

Description

The disclosed vulnerability allows a remote attacker to perform SSRF attacks.

The vulnerability exists due to insufficient validation of user-supplied input when the package relies on Java SAX Parser to implement its XML-RPC interface and by default that parser supports external entities in XML DOCTYPE. A remote attacker can send a specially crafted HTTP request to the affected application and trick it to initiate requests to arbitrary systems.

Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.

Mitigation
Install updates from vendor's website.

Vulnerable software versions
