CVE-2018-8005

Status: ModifiedMedium (5.3)—

When there are multiple ranges in a range request, Apache Traffic Server (ATS) will read the entire object from cache. This can cause performance problems with large objects in cache. This affects versions 6.0.0 to 6.2.2 and 7.0.0 to 7.1.3. To resolve this issue users running 6.x users should upgrade to 6.2.3 or later versions and 7.x users should upgrade to 7.1.4 or later versions.

CVSS

Exploitation probability (EPSS)

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).
