# CVE-2018-10852: Information disclosure in sssd > Local attackers can read sudo rules for any user due to overly permissive UNIX pipe permissions in SSSD communication. - **Severity:** Low 3.8 (`CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N`) - **Exploited in the wild:** Not known - **Login needed:** Any signed-in user - **Attackable:** Local or same network only - **Victim action needed:** Not needed - **Fix available:** Yes - **Published:** 26 Jun 2018 - **Updated:** 5 Aug 2024 - **Also known as:** DEBIAN-CVE-2018-10852, DLA-1429-1, GHSA-fw39-25vp-7459, MGASA-2018-0350, RHSA-2018:3158, SUSE-SU-2018:2144-1, SUSE-SU-2019:0081-1, UBUNTU-CVE-2018-10852 ## What is CVE-2018-10852? CVE-2018-10852 is a low-severity vulnerability in Debian Debian Linux, published on 26 Jun 2018. It can only be exploited from the same machine or local network, with no action from the victim. ### Official description The UNIX pipe which sudo uses to contact SSSD and read the available sudo rules from SSSD has too wide permissions, which means that anyone who can send a message using the same raw protocol that sudo and SSSD use can read the sudo rules available for any user. This affects versions of SSSD before 1.16.3. Weakness: CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor) ## Which versions are affected by CVE-2018-10852?

What it is: CVE-2018-10852 is a low-severity vulnerability in Debian Debian Linux, published on 26 Jun 2018. It can only be exploited from the same machine or local network, with no action from the victim. Exploitation: There is no known exploitation of CVE-2018-10852 in the wild and no public exploit code. Affected product: Debian Debian Linux. 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.
