What is CVE-2023-49735?
CVE-2023-49735 is a high-severity path traversal vulnerability in Apache Tiles, published on 30 Nov 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
** UNSUPPORTED WHEN ASSIGNED **
The value set as the DefaultLocaleResolver.LOCALE_KEY attribute on the session was not validated while resolving XML definition files, leading to possible path traversal and eventually SSRF/XXE when passing user-controlled data to this key. Passing user-controlled data to this key may be relatively common, as it was also used like that to set the language in the 'tiles-test' application shipped with Tiles.
This issue affects Apache Tiles from version 2 onwards.
NOTE: This vulnerability only affects products that are no longer supported by the maintainer.
Weakness: CWE-22
