## What is CVE-2017-12354?

CVE-2017-12354 is a medium-severity vulnerability in Cisco Secure Access Control System, published on 30 Nov 2017. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

A vulnerability in the web-based interface of Cisco Secure Access Control System (ACS) could allow an unauthenticated, remote attacker to view sensitive information on an affected system. The vulnerability exists because the affected software does not sufficiently protect system software version information when the software responds to HTTP requests that are sent to the web-based interface of the software. An attacker could exploit this vulnerability by sending crafted HTTP requests to the web-based interface of the affected software. A successful exploit could allow the attacker to view sensitive information about the software, which the attacker could use to conduct additional reconnaissance attacks. Cisco Bug IDs: CSCvf66155.

Weakness: CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor)

Check this codebase for CVE-2017-12354 and fix it if it is affected.

What it is: CVE-2017-12354 is a medium-severity vulnerability in Cisco Secure Access Control System, published on 30 Nov 2017. 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-2017-12354 in the wild and no public exploit code.

Affected product: Cisco Secure Access Control System. 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.
