Known exploited

CISA added this to the Known Exploited Vulnerabilities Catalog on 1 Jul 2025. US federal agencies had to remediate by 22 Jul 2025, a deadline that has passed.

Required action. Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.

Description

The TeleMessage service through 2025-05-05 is based on a JSP application in which the heap content is roughly equivalent to a "core dump" in which a password previously sent over HTTP would be included in this dump, as exploited in the wild in May 2025.
