Cisco today has released security updates to address critical remote code execution (RCE), authentication bypass, and static default credential vulnerabilities affecting multiple router and firewall devices that could lead to full device takeover.
Cisco also issued a security update to patch a privilege escalation vulnerability in the Cisco Prime License Manager software.
According to the company, there are no workarounds that could be applied to address these vulnerabilities.
The five security flaws patched today received 9.8 CVSS base score qualitative severity ratings from Cisco which makes them all critical vulnerabilities.
