Status: ModifiedHigh (7.2)—💥 Exploit

Vulnerability in telnetd in FreeBSD 1.5 allows local users to gain root privileges by modifying critical environmental variables that affect the behavior of telnetd.

CVSS

Version: 2.0
Vector: AV:L/AC:L/Au:N/C:C/I:C/A:C
Base score: 7.2

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 0.68%
Percentile among all scored CVEs: 51
Score date: 10/8/2026

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.
