What is CVE-2023-3533?

A vulnerability in the file upload functionality within Chamilo LMS versions up to 1.11.20 allows unauthenticated attackers to exploit a path traversal issue. This can lead to stored cross-site scripting (XSS) attacks and enables malicious users to write arbitrary files, potentially leading to remote code execution. Attackers can manipulate the application to access files outside of the intended directory, compromising the integrity of the system. It is crucial for affected users to apply available patches to mitigate this risk.

Affected Version(s)
