CVE-2025-3509: Software Security Vulnerability Vulnerability
HIGHCVE-2025-3509 is a HIGH (CVSS 7.2) security vulnerability vulnerability (CWE-94: Improper Control of Generation of Code ('Code Injection')) affecting Software libraries in the Maven ecosystem. The weakness occurs when the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.. Remediation is available in the latest vendor maintenance releases.
CVE-2025-3509 at a Glance
Security Impact
CVSS: 7.2
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H).
How to Fix CVE-2025-3509
To remediate this vulnerability, upgrade all affected Software dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:treeHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2025-3509, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:treeAnalyze the terminal output to locate any version of Software in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.
Note: The mvn dependency:tree command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In Software, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

"details" : "A Remote Code Execution (RCE) vulnerability was identified in GitHub Enterprise Server that allowed attackers to execute arbitrary code by exploiting the pre-receive hook functionality, potentially leading to privilege escalation and system compromise. The vulnerability involves using dynamically allocated ports that become temporarily available, such as during a hot patch upgrade. This means the vulnerability is only exploitable during specific operational conditions, which limits the attack window. Exploitation required either site administrator permissions to enable and configure pre-receive hooks or a user with permissions to modify repositories containing pre-receive hooks where this functionality was already enabled. This vulnerability affected all versions of GitHub Enterprise Server prior to 3.17 and was fixed in versions 3.16.2, 3.15.6, 3.14.11, 3.13.14. This vulnerability was reported via the GitHub Bug Bounty program.",
