Summary
Red Hat Security Advisory: : : : Updated wget packages fix directory traversal bug
Severity
Moderate
Notes
Topic: The wget packages shipped with Red Hat Linux 6.2 through 8.0 contain a security bug which, under certain circumstances, can cause local files to be written outside the download directory. [Updated 10 July 2003] Added packages for Red Hat Linux on IBM iSeries and pSeries systems
Details: Versions of wget prior to 1.8.2-4 contain a bug that permits a malicious FTP server to create or overwrite files anywhere on the local file system. FTP clients must check to see if an FTP server's response to the NLST command includes any directory information along with the list of filenames required by the FTP protocol (RFC 959, section 4.1.3). If the FTP client fails to do so, a malicious FTP server can send filenames beginning with '/' or containing '/../' which can be used to direct a vulnerable FTP client to write files (such as .forward, .rhosts, .shost, etc.) that can then be used for later attacks against the client machine. All Red Hat Linux users using wget < 1.8.2-4 should upgrade to the errata packages which are not vulnerable to this issue. Thanks to Steven M. Christey for his work in discovering this issue in current FTP clients and for providing a patched FTP server to verify the new packages.

CVE-2002-1344

Directory traversal vulnerability in wget before 1.8.2-4 allows a remote FTP server to create or overwrite files as the wget user via filenames containing (1) /absolute/path or (2) .. (dot dot) sequences.

Nomenclature

  • Seen: The vulnerability was mentioned, discussed, or observed by the user.
  • Confirmed: The vulnerability has been validated from an analyst's perspective.
  • Published Proof of Concept: A public proof of concept is available for this vulnerability.
  • Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
  • Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
  • Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
  • Not confirmed: The user expressed doubt about the validity of the vulnerability.
  • Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
