Proofpoint Insider Threat Management Server Remote Code Execution Deserialization Vulnerability
Description

Proofpoint Insider Threat Management Server contains an unsafe deserialization vulnerability in the Web Console. An attacker with write access to the local database could cause arbitrary code to execute with SYSTEM privileges on the underlying server when a Web Console user triggers retrieval of that data. When chained with a SQL injection vulnerability, the vulnerability could be exploited remotely if Web Console users click a series of maliciously crafted URLs. All versions prior to 7.11.2 are affected.
