What is CVE-2021-34789?

CVE-2021-34789 is a medium-severity cross-site scripting vulnerability in Cisco Secure Workload, published on 21 Oct 2021. An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.

Official description

A vulnerability in the web-based management interface of Cisco Tetration could allow an authenticated, remote attacker to perform a stored cross-site scripting (XSS) attack on an affected system. This vulnerability exists because the web-based management interface does not sufficiently validate user-supplied input. An attacker could exploit this vulnerability by injecting malicious code into specific pages of the interface. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information. To exploit this vulnerability, the attacker would need valid administrative credentials.
