A vulnerability in the web-based management interface of Cisco Prime Infrastructure and Evolved Programmable Network (EPN) Manager could allow an authenticated, remote attacker to execute arbitrary commands on an affected system. The vulnerability is due to insufficient validation of user-supplied input to the web-based management interface. An attacker could exploit this vulnerability by sending crafted HTTP requests to the interface. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system (OS) with the permissions of a special non-root user. In this way, an attacker could take control of the affected system, which would allow them to obtain and alter sensitive data. The attacker could also affect the devices that are managed by the affected system by pushing arbitrary configuration files, retrieving device credentials and confidential information, and ultimately undermining the stability of the devices, causing a denial of service (DoS) condition.

Detection & IOCsextracted from sources · hover to see the quote
- →Exploit vector is crafted HTTP requests to the web-based management interface of Cisco Prime Infrastructure or EPN Manager; monitor for anomalous or malformed HTTP requests targeting these management interfaces from authenticated sessions. ↗
- →Successful exploitation results in OS command execution as a special non-root user; monitor for unexpected process spawning from the Cisco Prime Infrastructure or EPN Manager web application process (e.g., shell processes forked from the Java/web container). ↗
- →Post-exploitation activity may include pushing arbitrary configuration files to managed devices or retrieving device credentials; monitor for unexpected configuration pushes or credential access originating from the Prime Infrastructure / EPN Manager server. ↗
- →Track Cisco Bug IDs CSCvw07763 and CSCvw67903 for patch status; use these identifiers when querying Cisco PSIRT or internal asset management to identify unpatched instances. ↗
- ·Exploitation requires prior authentication; attack surface is limited to authenticated users of the web-based management interface. Prioritize monitoring and patching for environments where a broad set of users have access to the PI/EPNM management interface. ↗
- ·There are no workarounds available; patching via Cisco software updates is the only remediation. Ensure affected Cisco Prime Infrastructure and EPN Manager instances are updated promptly. ↗
- ·The vulnerability is classified as CWE-78 (OS Command Injection) with a CVSS score of 3.1 base; input validation controls on the web management interface are insufficient and should not be relied upon as a compensating control. ↗
