Source: undertow Version: 1.4.8-1+deb9u1 Severity: grave Tags: security Forwarded: https://issues.jboss.org/browse/UNDERTOW-1245
It was found that the AJP connector in undertow, as shipped in Jboss EAP 7.1.0.GA, does not use the ALLOW_ENCODED_SLASH option and thus allow the the slash / anti-slash characters encoded in the url which may lead to path traversal and result in the information disclosure of arbitrary local files. Upstream bug: https://issues.jboss.org/browse/UNDERTOW-1245 This was apparently fixed in 1.4.22.
