SB2019060306 - SSRF in Apache Roller

Description

This security bulletin contains information about 1 vulnerability.

1) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2018-17198)

CWE-ID: CWE-918 - Server-Side Request Forgery (SSRF)

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green

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.

Remediation
