MediumCVSS 6.7 · v3.1—No exploit No fix recorded

Noroxi assessment

Priority: Monitor (action score 26/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.16% (FIRST EPSS).
  • Someone with local access to the system can trigger it. Administrator privileges are required. No user action is required. No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.
  • Severity is disputed: the assigning authority (CNA) scores it 4.4, NVD 6.7.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS

A vulnerability in the CLI of Cisco SD-WAN vManage Software could allow an authenticated, local attacker to elevate privileges on an affected system. To exploit this vulnerability, an attacker would need to have a valid Administrator account on an affected system. The vulnerability is due to incorrect privilege assignment. An attacker could exploit this vulnerability by logging in to an affected system with an Administrator account and creating a malicious file, which the system would parse at a later time. A successful exploit could allow the attacker to obtain root privileges on the affected system.Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
