CVE-2007-4004

Status: ModifiedMedium (6.9)—Exploit
Severity6.9Medium · CVSS 2.0
Exploitation probability0.85 %higher than 58% of CVEs
Active exploitationNonot in the CISA catalog
Public exploitAvailablePublished on Exploit-DB

Buffer overflow in the ftp client in IBM AIX 5.3 SP6 and 5.2.0 allows local users to execute arbitrary code via unspecified vectors that trigger the overflow in a gets function call. NOTE: the client is setuid root on AIX, so this issue crosses privilege boundaries.

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.
