A vulnerability, which was classified as problematic, was found in Cisco Small Business SA520 and Small Business SA540 2.1.71/2.2.0.7. This affects some unknown functionality of the file scgi-bin/platform.cgi. The manipulation of the argument thispage
with the input value ../
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. The summary by CVE is:
Cisco Small Business SA520 and SA540 devices with firmware 2.1.71 and 2.2.0.7 allow ../ directory traversal in scgi-bin/platform.cgi via the thispage parameter, for reading arbitrary files.
