AI Analysis
Technical Summary
This vulnerability (CWE-404) in AWS Wickr desktop clients before version 6.62.13 results from improper resource release during the call termination process. Specifically, under certain conditions requiring user interaction, a participant may continue to receive audio input from another user even after closing their call window. The CVSS 3.1 base score is 5.7 (medium), reflecting network attack vector, low attack complexity, required privileges, and user interaction, with high confidentiality impact but no integrity or availability impact. The issue affects Windows, macOS, and Linux versions of AWS Wickr, Wickr Gov, and Wickr Enterprise. AWS has provided an official fix in version 6.62.13.
Potential Impact
An attacker or call participant could continue to receive audio input from another user after the call window is closed, potentially exposing sensitive audio communications. The confidentiality impact is high, but integrity and availability are not affected. Exploitation requires user interaction and some privileges within the application. There are no known exploits in the wild at this time.
Mitigation Recommendations
Users should upgrade AWS Wickr, Wickr Gov, and Wickr Enterprise desktop clients to version 6.62.13 or later to remediate this vulnerability. No other mitigations are indicated or required by the vendor advisory.
