# CVE-2007-1349: Denial of service in n/a > Remote attackers can cause a denial of service via resource consumption by sending a crafted URI to Apache mod_perl due to improper PATH_INFO escaping. - **Severity:** Medium 5.0 (`AV:N/AC:L/Au:N/C:N/I:N/A:P`) - **Exploited in the wild:** Not known - **Login needed:** Not needed - **Attackable:** Over the internet - **Victim action needed:** Not needed - **Fix available:** Yes - **Published:** 30 Mar 2007 - **Updated:** 7 Aug 2024 - **Also known as:** DEBIAN-CVE-2007-1349, GHSA-fxxc-hq33-c3m6, RHSA-2007:0395, RHSA-2007:0396, RHSA-2007:0486, RHSA-2008:0627 ## What is CVE-2007-1349? CVE-2007-1349 is a medium-severity denial of service vulnerability in Canonical Ubuntu Linux, published on 30 Mar 2007. An attacker can exploit it over the internet without logging in, with no action from the victim. ### Official description PerlRun.pm in Apache mod_perl before 1.30, and RegistryCooker.pm in mod_perl 2.x, does not properly escape PATH_INFO before use in a regular expression, which allows remote attackers to cause a denial of service (resource consumption) via a crafted URI.

What it is: CVE-2007-1349 is a medium-severity denial of service vulnerability in Canonical Ubuntu Linux, published on 30 Mar 2007. 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-2007-1349 in the wild and no public exploit code. Affected product: Canonical Ubuntu 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.
