Detailsinfo

A vulnerability has been found in Mytty Webapplication Finger Printer 0.01-26c3 (Printing Software) and classified as problematic. Affected by this vulnerability is some unknown processing in the library lib/wafp_pidify.rb. The manipulation with an unknown input leads to a symlink vulnerability. The CWE definition for the vulnerability is CWE-61. The product, when opening a file or directory, does not sufficiently account for when the file is a symbolic link that resolves to a target outside of the intended control sphere. This could allow an attacker to cause the product to operate on unauthorized files. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Web Application Finger Printer (WAFP) 0.01-26c3 uses fixed pathnames under /tmp for temporary files and directories, which (1) allows local users to cause a denial of service (application outage) by creating a file with a pathname that the product expects is available for its own internal use, (2) allows local users to overwrite arbitrary files via symlink attacks on certain files in /tmp, (3) might allow local users to delete arbitrary files and directories via a symlink attack on a directory under /tmp, and (4) might make it easier for local users to obtain sensitive information by reading files in a directory under /tmp, related to (a) lib/wafp_pidify.rb, (b) utils/generate_wafp_fingerprint.sh, (c) utils/online_update.sh, and (d) utils/extract_from_db.sh.
