## What is CVE-2023-49110?

CVE-2023-49110 is a high-severity vulnerability in Kiuwan SAST, published on 20 Jun 2024. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

When the Kiuwan Local Analyzer uploads the scan results to the Kiuwan SAST web 
application (either on-premises or cloud/SaaS solution), the transmitted data 
consists of a ZIP archive containing several files, some of them in the 
XML file format. During Kiuwan's server-side processing of these XML 
files, it resolves external XML entities, resulting in a XML external 
entity injection attack. An attacker with privileges to scan 
source code within the "Code Security" module is able to extract any 
files of the operating system with the rights of the application server 
user and is potentially able to gain sensitive files, such as 
configuration and passwords. Furthermore, this vulnerability also allows
 an attacker to initiate connections to internal systems, e.g. for port 
scans or accessing other internal functions / applications such as the 
Wildfly admin console of Kiuwan.

This issue affects Kiuwan SAST: <master.1808.p685.q13371

Weakness: CWE-611 (Improper Restriction of XML External Entity Reference)

Check this codebase for CVE-2023-49110 and fix it if it is affected.

What it is: CVE-2023-49110 is a high-severity vulnerability in Kiuwan SAST, published on 20 Jun 2024. An attacker needs administrator access to exploit it, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-49110 exists.

Affected product: Kiuwan SAST. 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.
