CVE-2022-50694: SOUND4 IMPACT/FIRST/PULSE/Eco <=2.x SQL Injection via Username Parameter

Noroxi assessment

Priority: Monitor (action score 35/100)

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: 0.88% (FIRST EPSS); higher than 59.2% 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.
According to the record, no fixed version is available yet.

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS

SOUND4 IMPACT/FIRST/PULSE/Eco <=2.x contains an SQL injection vulnerability in the 'username' POST parameter of index.php that allows attackers to manipulate database queries. Attackers can inject arbitrary SQL code through the username parameter to bypass authentication and potentially access unauthorized database information.
