U.S. Cybersecurity and Infrastructure Security Agency (CISA) added a second security flaw affecting BeyondTrust’s Privileged Remote Access (PRA) and Remote Support (RS) products to its Known Exploited Vulnerabilities (KEV) catalog, noting that it is actively being exploited.
CVE-2024-12686 is a medium-severity vulnerability (CVSS score: 6.6) that could let an attacker with admin privileges inject commands and execute them as a site user.

“BeyondTrust Privileged Remote Access (PRA) and Remote Support (RS) contain an OS command injection vulnerability that can be exploited by an attacker with existing administrative privileges to upload a malicious file,” CISA said.
“Successful exploitation of this vulnerability can allow a remote attacker to execute underlying operating system commands within the context of the site user.”
“The addition of CVE-2024-12686 to the KEV catalog comes nearly a month after it added another critical security issue affecting the same product that could also allow remote command execution.”
BeyondTrust stated that both vulnerabilities were found during an investigation into a cyber incident in early December 2024, where attackers used a stolen Remote Support API key to access some systems and change local account passwords.
The API key has been revoked, but it’s unclear how it was compromised. It’s believed that attackers used two zero-day vulnerabilities to access BeyondTrust systems.
