ValveLink SOLO: Cleartext Storage of Sensitive Information in Memory
CVE-2025-52579 is a critical-severity cleartext storage of sensitive information in memory vulnerability in ValveLink SOLO from Emerson, with a CVSS 3.1 base score of 9.4 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version ValveLink 14.0 as the first without the flaw, so updating ValveLink SOLO to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.39% chance of exploitation within 30 days, which is low compared with other CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update ValveLink SOLO to ValveLink 14.0 or a later version.
- Update ValveLink DTM to ValveLink 14.0 or a later version.
- Update ValveLink PRM to ValveLink 14.0 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
