CVE-2024-13136: Medium Deserialization in mysiteforme 1.0

CVE-2024-13136 is a medium severity (CVSS 6.3) insecure deserialization flaw in wangl1989 mysiteforme 1.0, in the rememberMeManager function of ShiroConfig.java. The record says the exploit has been disclosed publicly. No fixed version is named, so check the project issue and limit exposure of the admin area.

What's affected

• wangl1989 mysiteforme version 1.0.
• The affected code is rememberMeManager in src/main/java/com/mysiteforme/admin/config/ShiroConfig.java.

The record names no fixed version, and it describes the exploit as publicly disclosed. Check the project's issue tracker and repository for a patch. If none exists, treat the project as unfixed.

How to check if you're exposed

Run the check below, or read the vendor or project notes linked in Sources.

# Look at your build file for the project and its version
grep -n -i mysiteforme pom.xml

Compare the result to the affected range above.

What to do now

1. Check whether you run mysiteforme 1.0 anywhere, including internal demos.
2. Read the project issue linked below for the maintainer's response.
3. Review how the application sets up Apache Shiro's remember-me feature. Shiro's remember-me cookie is processed by the server, so its key and handling are security critical.
4. Put the admin interface behind a network control until the code is patched.
5. Look up CVE-2024-13136 on its Gold page to see the current details and any fix information.
6. Check your own dependency files with the free in-browser dependency scan. It runs in your browser and does not send the file to a server.

Why it matters

The record points at the function that builds the remember-me manager in the Shiro configuration. The weakness classes are improper input validation and deserialization of untrusted data. In a Shiro based application the remember-me cookie is read back by the server, so how that cookie is protected decides whether an outsider can influence what gets deserialized.

The score is medium because the vector requires a low privilege account and rates each impact as low. That is still a serious design problem to correct, because deserialization bugs tend to be worse than their first rating suggests when gadget classes are present on the classpath.

This CVE is an insecure deserialization flaw (CWE-20, CWE-502, Improper Input Validation and Deserialization of Untrusted Data). Nothing in the record says it is exploited in the wild, and it is not marked as listed in CISA's Known Exploited Vulnerabilities catalog. That is a snapshot, so keep checking.

Deserialization turns stored or transmitted bytes back into live objects. If the bytes come from an untrusted party, the object that gets built, and the code that runs while building it, are partly chosen by that party.

The safe approach is to avoid native object serialization for untrusted data, use a plain data format such as JSON, and sign or encrypt anything that must round trip through the browser.
