CVE-2019-11454
Status: ModifiedMedium (6.1)—
Persistent cross-site scripting (XSS) in http/cervlet.c in Tildeslash Monit before 5.25.3 allows a remote unauthenticated attacker to introduce arbitrary JavaScript via manipulation of an unsanitized user field of the Authorization header for HTTP Basic Authentication, which is mishandled during an _viewlog operation.
CVSS
- Version: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
- Base score: 6.1
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 2.41%
- Percentile among all scored CVEs: 84
- Score date: 10/5/2026
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).
