CVE-2023-28500 is a critical-severity vulnerability affecting adobe livecycle_es4. It was published on April 6, 2023 and has a CVSS 3.1 base score of 9.8 (CRITICAL).
This vulnerability has a CVSS 3.1 base score of 9.8, rated CRITICAL. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
A Java insecure deserialization vulnerability in Adobe LiveCycle ES4 version 11.0 and earlier allows unauthenticated remote attackers to gain operating system code execution by submitting specially crafted Java serialized objects to a specific URL. Adobe LiveCycle ES4 version 11.0.1 and later may be vulnerable if the application is installed with Java environment 7u21 and earlier. Exploitation of the vulnerability depends on two factors: insecure deserialization methods used in the Adobe LiveCycle application, and the use of Java environments 7u21 and earlier. The code execution is performed in the context of the account that is running the Adobe LiveCycle application. If the account is privileged, exploitation provides privileged access to the operating system. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.
Remediation
Check the references section for vendor advisories and patches from adobe. Update livecycle_es4 to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
