What happened 🕵️‍♂️

A vulnerability in a subset of REST APIs of Cisco Prime Infrastructure and Cisco Evolved Programmable Network Manager (EPNM) could allow an authenticated, low-privileged, remote attacker to conduct a blind SQL injection attack.

This vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by sending a crafted request to an affected API. A successful exploit could allow the attacker to view data in some database tables on an affected device.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

For leadership 🧭

Executive summary. Cisco Prime Infrastructure and Evolved Programmable Network Manager contain a REST API flaw that lets any logged-in, low-privileged user extract data from backend database tables through blind SQL injection. There are no workarounds, so remediation depends on scheduling the vendor’s fixed release for your affected train.

Why it matters:

• The flaw sits in a subset of REST APIs on Prime Infrastructure and EPNM, tools typically used to manage network device inventory, configuration and monitoring data.
• Any authenticated user, not just an administrator, can send a crafted API request to read data from database tables on the affected system.
• Cisco has not published a workaround, so exposure persists until the affected train is upgraded to the fixed release listed in the advisory.
• Prime Infrastructure and EPNM often hold configuration and credential-adjacent data for managed network estates, making unauthorised table reads a route to broader network reconnaissance.

Now / Next / Later:

• Now: Identify every Prime Infrastructure and EPNM instance in your estate and confirm which release train each is running against the fixed-release table.
• Next: Schedule an upgrade to the first fixed release for your train (8.0.1, 8.1.1, or 3.10.6 Security Update 02), or migrate off unsupported 7.1/3.9-and-earlier trains, since no workaround exists.
• Later: Review who holds accounts on Prime Infrastructure and EPNM and tighten low-privilege access, since this issue shows standard authenticated users can reach sensitive backend data through the REST API.
