NVD · unedited
Allegra loadFieldMatch Deserialization of Untrusted Data Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Allegra. Authentication is required to exploit this vulnerability. The specific flaw exists within the loadFieldMatch method. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code in the context of LOCAL SERVICE. Was ZDI-CAN-23452.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

This is a deserialization vulnerability in the loadFieldMatch method of Allegra. The method lacks proper validation of user-supplied data, allowing deserialization of untrusted data. An authenticated attacker can exploit this to achieve remote code execution in the context of the LOCAL SERVICE account.

MitigationImplement strict input validation on the loadFieldMatch method and avoid deserializing untrusted data. If deserialization is required, use safe deserialization formats or whitelist expected types.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Verify Allegra is installed
    Check for Allegra application files or service running on the system. Look for the allegra process or web application directory.
    Affected if Allegra software is found running on the system
  2. Determine installed Allegra version
    Check the application's version information, typically found in the About section, a version file, or the application metadata (e.g., MANIFEST.MF, version.properties, or the web interface footer).
    Affected if The installed version is any version below 7.5.2 (e.g., 7.5.1, 7.5.0, 7.4.x, etc.)
  3. Confirm loadFieldMatch method accessibility
    Inspect if the loadFieldMatch API endpoint or method is exposed and accessible within the application. This is typically found in the application's API documentation, routing configuration, or by checking available web service endpoints.
    Affected if The loadFieldMatch method is accessible without additional authentication or with standard user authentication
  4. Verify authentication controls on the method
    Review the application's security configuration or authentication settings to determine if the loadFieldMatch method enforces proper authentication and authorization before processing requests.
    Affected if The loadFieldMatch method can be invoked by authenticated users without additional hardening or input validation safeguards
  5. Check deserialization configuration
    Review application configuration files or settings related to object deserialization. Look for configurations that allow Java deserialization or similar mechanisms used by the loadFieldMatch method.
    Affected if Deserialization of untrusted data is permitted without type checking or input validation on the loadFieldMatch method

The environment is affected if Allegra (Alltena Allegra) is installed with a version lower than 7.5.2 and the loadFieldMatch method is accessible to authenticated users without proper input validation on deserialized data.
