CVE-2017-17533

High
Published: Translated: NVD NIST

Summary

The default.tcl file in Tkabber 1.1 does not validate strings before launching the program specified by the BROWSER environment variable, which may allow remote attackers to conduct argument-injection attacks via a crafted URL.

Risk Assessment

Attackers may exploit this vulnerability to inject malicious arguments, potentially leading to unauthorized access or execution of harmful commands. However, there is information suggesting that the attack may be limited by the argument-parsing behavior of the Tcl exec function.

Recommendation

It is recommended to update Tkabber to the latest version and implement additional input validation mechanisms before processing the input data.
