Status: ModifiedLow (2.6)—
The Apache HTTP Server 2.0.44, when DNS resolution is enabled for client IP addresses, allows remote attackers to inject arbitrary text into log files via an HTTP request in conjunction with a crafted DNS response, as demonstrated by injecting XSS sequences, related to an "Inverse Lookup Log Corruption (ILLC)" issue.
CVSS
- Version: 2.0
- Vector: AV:N/AC:H/Au:N/C:N/I:P/A:N
- Base score: 2.6
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 3.08%
- Percentile among all scored CVEs: 87
- Score date: 10/7/2026
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).
