Cisco announced patches for eight vulnerabilities in the IOS XR network operating system, including fixes for six high-severity bugs. The most severe flaws allow privilege escalation and remote DoS attacks. Two high-severity flaws affecting the Routed Passive Optical Network (PON) controller software could be exploited for command injection. Cisco plans to resolve them with future updates.
After carefully reviewing the meeting notes, the following key takeaways can be summarized:
1. Cisco announced patches for eight vulnerabilities in the IOS XR network operating system, including fixes for six high-severity bugs.
2. The most severe vulnerability is CVE-2024-20398 with a CVSS score of 8.8, which results from insufficient validation of user arguments passing to specific CLI commands, allowing for privilege elevation.
3. Another high-severity bug, CVE-2024-20304 with a CVSS score of 8.6, impacts the Mtrace2 feature of IOS XR, causing a denial-of-service condition through remote exploitation without authentication.
4. Two high-severity flaws affect the Routed Passive Optical Network (PON) controller software and can be exploited for command injection, enabling attackers to execute commands as root or retrieve MongoDB credentials.
5. Cisco also announced fixes for two other high-severity DoS flaws in its network OS, as well as two medium-severity bugs in IOS XR.
6. The company stated that it is not aware of any of these vulnerabilities being exploited in the wild and provided additional information in the semiannual IOS XR software security advisory.
