Deserialization of Untrusted Data

CVE-2024-55638

High
7.5/10

Summary

Deserialization of Untrusted Data vulnerability in Drupal Core allows Object Injection. This issue affects Drupal Core versions 7.0 through 7.101, 8.0.0-alpha2 through 10.2.10, and 10.3.0-beta1 through 10.3.8. Drupal core contains a chain of methods that is exploitable when an insecure deserialization vulnerability exists on the site. This so-called gadget chain presents no direct threat but is a vector that can be used to achieve remote code execution if the application deserializes untrusted data due to another vulnerability.

CWE-502 - Deserialization of Untrusted Data

Deserialization of untrusted data vulnerabilities enable an attacker to replace or manipulate a serialized object, replacing it with malicious data. When the object is deserialized at the victim's end the malicious data is able to compromise the victim’s system. The exploit can be devastating, its impact may range from privilege escalation, broken access control, or denial of service attacks to allowing unauthorized access to the application's internal code and logic which can compromise the entire system.
