Noroxi assessment
Priority: Monitor (action score 17/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 23% (FIRST EPSS); higher than 97.7% of all records.
- Special conditions such as timing or configuration are required.
- Fixed version: apache2 (Debian:12) 2.2.22-8; mod_ssl (Red Hat:enterprise_linux:5::client) 1:2.2.3-74.el5; httpd (Red Hat:enterprise_linux:5::client_workstation) 0:2.2.3-74.el5.
Low priority for now. Upgrade to apache2 (Debian:12) 2.2.22-8; mod_ssl (Red Hat:enterprise_linux:5::client) 1:2.2.3-74.el5; httpd (Red Hat:enterprise_linux:5::client_workstation) 0:2.2.3-74.el5 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
Multiple cross-site scripting (XSS) vulnerabilities in the make_variant_list function in mod_negotiation.c in the mod_negotiation module in the Apache HTTP Server 2.4.x before 2.4.3, when the MultiViews option is enabled, allow remote attackers to inject arbitrary web script or HTML via a crafted filename that is not properly handled during construction of a variant list.
