CVE-1999-1588

Status: ModifiedCritical (9.8)—💥 Exploit

Buffer overflow in nlps_server in Sun Solaris x86 2.4, 2.5, and 2.5.1 allows remote attackers to execute arbitrary code as root via a long string beginning with "NLPS:002:002:" to the listen (aka System V listener) port, TCP port 2766.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

💥 Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
