# CVE-2021-1487: Cisco Prime Infrastructure and Cisco Evolved Programmable Network Manager Command Injection Vulnerability > Authenticated attackers can execute arbitrary commands on Cisco Prime Infrastructure and EPN Manager, potentially compromising managed devices and sensitive data. - **Severity:** High 8.8 (`CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H`) - **Exploited in the wild:** Not known - **Login needed:** Any signed-in user - **Attackable:** Over the internet - **Victim action needed:** Not needed - **Fix available:** No - **Published:** 22 May 2021 - **Updated:** 8 Nov 2024 - **Also known as:** GHSA-5frr-j9x3-j3hg ## What is CVE-2021-1487? CVE-2021-1487 is a high-severity command injection vulnerability in Cisco Evolved Programmable Network Manager, published on 22 May 2021. Any signed-in user can exploit it over the network, with no action from the victim. ### Official description 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. Weakness: CWE-78 (Improper Neutralization of Special Elements used in an OS Command) ## Which versions are affected by CVE-2021-1487? It affects 2 products. Products: Cisco Evolved Programmable Network Manager, Cisco Prime Infrastructure. ## How do I fix CVE-2021-1487? No fix has been published for CVE-2021-1487 yet.

What it is: CVE-2021-1487 is a high-severity command injection vulnerability in Cisco Evolved Programmable Network Manager, published on 22 May 2021. Any signed-in user can exploit it over the network, with no action from the victim. Exploitation: There is no known exploitation of CVE-2021-1487 in the wild and no public exploit code. Affected product: Cisco Evolved Programmable Network Manager. No package-level version data is available, so check the vendor advisory linked from the reference page. Task: 1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies. 2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it. 3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead. 4. Run the tests and summarise what changed and why. 5. If nothing in the project is affected, say so and change nothing.
