CVE-2023-49735

23
FAUCET Score

CVE-2023-49735 describes a path traversal vulnerability in Apache Tiles versions 2 and later. This flaw arises from the lack of validation on the DefaultLocaleResolver.LOCALE_KEY attribute in the session, which, when supplied with user-controlled data, could lead to Server-Side Request Forgery (SSRF) or XML External Entity (XXE) injection during XML definition file resolution. The vulnerability carries a CVSS v3.1 score of 7.5 (HIGH), indicating a network-based attack with low complexity and no user interaction required, potentially leading to high confidentiality impact. However, it's important to note that this vulnerability only affects products that are no longer supported by the maintainer. Currently, there is no evidence of active exploitation, nor are there publicly available exploit modules in Metasploit, Nuclei, or ExploitDB. Community discussion and media coverage for this CVE are minimal, suggesting a low level of public awareness or concern.
