## What is CVE-2018-0089?

CVE-2018-0089 is a high-severity vulnerability in Cisco Policy Suite, published on 18 Jan 2018. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

A vulnerability in the Policy and Charging Rules Function (PCRF) of the Cisco Policy Suite (CPS) could allow an unauthenticated, remote attacker to access sensitive data. The attacker could use this information to conduct additional reconnaissance attacks. The attacker would also have to have access to the internal VLAN where CPS is deployed. The vulnerability is due to incorrect permissions of certain system files and not sufficiently protecting sensitive data that is at rest. An attacker could exploit the vulnerability by using certain tools available on the internal network interface to request and view system files. An exploit could allow the attacker to find out sensitive information about the application. Cisco Bug IDs: CSCvf77666.

Weakness: CWE-732 (Incorrect Permission Assignment for Critical Resource), CWE-312 (Cleartext Storage of Sensitive Information), CWE-264

Check this codebase for CVE-2018-0089 and fix it if it is affected.

What it is: CVE-2018-0089 is a high-severity vulnerability in Cisco Policy Suite, published on 18 Jan 2018. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2018-0089 in the wild and no public exploit code.

Affected product: Cisco Policy Suite. 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.
