[GLSA-200511-16] GNUMP3d: Directory traversal and insecure temporary file creation |
||
GNUMP3d: Directory traversal and insecure temporary file creation Detailed Explanation for this Vulnerability Assessment The remote host is affected by the vulnerability described in GLSA-200511-16 (GNUMP3d: Directory traversal and insecure temporary file creation) Ludwig Nussel from SUSE Linux has identified two vulnerabilities in GNUMP3d. GNUMP3d fails to properly check for the existence of /tmp/index.lok before writing to the file, permiting for local unauthorized access to files owned by the user running GNUMP3d. GNUMP3d also fails to properly validate the "theme" GET variable from CGI input, permiting for unauthorized file inclusion. Impact A possible hacker could overwrite files owned by the user running GNUMP3d by symlinking /tmp/index.lok to the file targeted for overwrite. A possible hacker could also include arbitrary files by traversing up the directory tree (at most two times, i.e. "../..") with the "theme" GET variable. Workaround There is no known workaround at this time.
