CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability was found in Chilkat Software Chilkat Zip ActiveX control 12.4.2.0. It has been classified as critical. This affects an unknown code block in the library chilkatzip2.dll of the component ActiveX Control. The manipulation 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, and integrity. The summary by CVE is:

Absolute path traversal vulnerability in the Chilkat Software Chilkat Zip ActiveX control in ChilkatZip2.dll 12.4.2.0 allows remote attackers to create or overwrite arbitrary files via a full pathname in the argument to the (1) SaveLastError method and probably the (2) WriteExe method.
