Fix not verifiedA vulnerability in Veeam Service Provider Console allowing an unauthenticated attacker to exhaust host memory and cause adenial of service.
A vulnerability in Veeam Service Provider Console allowing an unauthenticated attacker to exhaust host memory and cause adenial of service.
The product allocates memory based on an untrusted, large size value, but it does not ensure that the size is within expected limits, allowing arbitrary amounts of memory to be allocated.
An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may disrupt the affected service.

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.
