## What is CVE-2018-1162?

CVE-2018-1162 is a high-severity path traversal vulnerability in Quest NetVault Backup, published on 8 Feb 2018. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

This vulnerability allows remote attackers to create a denial-of-service condition on vulnerable installations of Quest NetVault Backup 11.2.0.13. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be easily bypassed. The specific flaw exists within the handling of Export requests. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to arbitrarily overwrite files resulting in a denial-of-service condition. Was ZDI-CAN-4222.

Weakness: CWE-22 (Improper Limitation of a Pathname to a Restricted Directory)

What it is: CVE-2018-1162 is a high-severity path traversal vulnerability in Quest NetVault Backup, published on 8 Feb 2018. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2018-1162 in the wild and no public exploit code.

Affected product: Quest NetVault Backup. 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.
