CVE-2003-0083

Status: ModifiedMedium (5)—
Apache 1.3 before 1.3.25 and Apache 2.0 before version 2.0.46 does not filter terminal escape sequences from its access logs, which could make it easier for attackers to insert those sequences into terminal emulators containing vulnerabilities related to escape sequences, a different vulnerability than CVE-2003-0020.
CVSS

Version: 2.0
Vector: AV:N/AC:L/Au:N/C:N/I:P/A:N
Base score: 5
Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 17%
Percentile among all scored CVEs: 97
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).
