A vulnerability in the web-based management interface of Cisco Integrated Management Controller (IMC) Supervisor, Cisco UCS Director, and Cisco UCS Director Express for Big Data could allow an authenticated, remote attacker to execute arbitrary commands on the underlying Linux shell as the root user. Exploitation of this vulnerability requires privileged access to an affected device. The vulnerability is due to insufficient validation of user-supplied input by the web-based management interface. An attacker could exploit this vulnerability by logging in to the web-based management interface with administrator privileges and then sending a malicious request to a certain part of the interface.
CVE-2019-1936
Score elevated to 7.5 because EPSS predicts 39% probability of exploitation within the next 30 days (top 1.5% of all CVEs). NVD baseline CVSS 7.2 retained for reference. Confidence: see factors.
- Public exploit code is available (Metasploit, epss top5pct, public exploit)
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
