A vulnerability was found in Simplog 0.9.2. It has been classified as critical. This affects an unknown code block of the file /doc/index.php. The manipulation of the argument s with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Directory traversal vulnerability in doc/index.php in Jeremy Ashcraft Simplog 0.9.2 and earlier allows remote attackers to include and execute arbitrary local files via directory traversal sequences in the s parameter, as demonstrated by injecting PHP sequences into an Apache error_log file, which is then included by doc/index.php.
