## What is CVE-2023-51604?

CVE-2023-51604 is a medium-severity vulnerability in Honeywell Saia PG5 Controls Suite, published on 3 May 2024. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.

### Official description

Honeywell Saia PG5 Controls Suite XML External Entity Processing Information Disclosure Vulnerability. This vulnerability allows remote attackers to disclose sensitive information on affected installations of Honeywell Saia PG5 Controls Suite. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.

The specific flaw exists within the parsing of XML files. Due to the improper restriction of XML External Entity (XXE) references, a crafted document specifying a URI causes the XML parser to access the URI and embed the contents back into the XML document for further processing. An attacker can leverage this vulnerability to disclose information in the context of the current process.
. Was ZDI-CAN-18593.

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

What it is: CVE-2023-51604 is a medium-severity vulnerability in Honeywell Saia PG5 Controls Suite, published on 3 May 2024. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2023-51604 in the wild and no public exploit code.

Affected product: Honeywell Saia PG5 Controls Suite. 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.
