HighCVSS 7.5 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 30/100)

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: 0.68% (FIRST EPSS); higher than 52.8% of all records.
Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
According to CISA the attack is automatable: targets can be found by mass scanning.
Fixed version: suricata (Alpine:v3.21) 7.0.8-r0; suricata (Debian:13) 1:7.0.8-1.

Low priority for now. Upgrade to suricata (Alpine:v3.21) 7.0.8-r0; suricata (Debian:13) 1:7.0.8-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to 7.0.8, a large input buffer to the to_lowercase, to_uppercase, strip_whitespace, compress_whitespace, dotprefix, header_lowercase, strip_pseudo_headers, url_decode, or xor transform can lead to a stack overflow causing Suricata to crash. The issue has been addressed in Suricata 7.0.8.

Root cause

Code that parses nested structures sets no depth or size limit. A small input can turn into a disproportionate processing load.
