Cisco this week announced the release of software updates that address several vulnerabilities in Jabber for desktop and mobile platforms, the most severe of which could be abused to execute arbitrary code with elevated privileges.
The bugs impact Cisco Jabber for Windows, macOS, and mobile platforms, and are not dependable to one another.
The most important of them is CVE-2021-1411, a critical arbitrary program execution flaw in Jabber for Windows, which exists because of improper validation of message content.
Successful exploitation of this vulnerability could result in code execution, Cisco explains.
Next in line is CVE-2021-1469, a high-severity security hole in Jabber for Windows that, similarly to CVE-2021-1411, could lead to code execution.
Two other medium-severity flaws affect Jabber for Windows, Jabber for macOS, and Jabber for mobile platforms.
