CVE-2011-1143
Status: ModifiedMedium (4.3)—💥 Exploit
epan/dissectors/packet-ntlmssp.c in the NTLMSSP dissector in Wireshark before 1.4.4 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted .pcap file.
CVSS
- Version: 2.0
- Vector: AV:N/AC:M/Au:N/C:N/I:N/A:P
- Base score: 4.3
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 8.59%
- Percentile among all scored CVEs: 95
- Score date: 10/9/2026
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.
