Advisory Summary

CVE-2025-34337 is a HIGH security vulnerability vulnerability (CWE-345: Insufficient Verification of Data Authenticity) affecting Software libraries in the Maven ecosystem. The weakness occurs when the product does not sufficiently verify the origin or authenticity of data, in a way that causes it to accept invalid data.. Remediation is available in the latest vendor maintenance releases.

How to Fix CVE-2025-34337

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.

Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2025-34337, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree

Analyze 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-345: Insufficient Verification of Data Authenticity, where the product does not sufficiently verify the origin or authenticity of data, in a way that causes it to accept invalid data. 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.

Source Advisory Statement

eGovFramework/egovframe-common-components versions up to and including 4.3.1 includes Web Editor image upload and related file delivery functionality that uses symmetric encryption to protect URL parameters, but exposes an encryption oracle that allows attackers to generate valid ciphertext for chosen values. The image upload endpoints /utl/wed/insertImage.do and /utl/wed/insertImageCk.do encrypt server-side paths, filenames, and MIME types and embed them directly into a download URL that is returned to the client. Because these same encrypted parameters are trusted by other endpoints, such as /utl/web/imageSrc.do and /cmm/fms/getImage.do, an unauthenticated attacker can abuse the upload functionality to obtain encrypted representations of attacker-chosen identifiers and then replay those ciphertext values to file-serving APIs. This design failure allows an attacker to bypass access controls that rely solely on the secrecy of encrypted parameters and retrieve arbitrary stored files that are otherwise expected to require an existing session or specific authorization context. KISA/KrCERT has identified this unpatched vulnerability as "KVE-2023-5281."
