CVE-2024-21782: BIG-IP and BIG-IQ secure copy vulnerability

Noroxi assessment

Priority: Monitor (action score 26/100)

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: 0.17% (FIRST EPSS).
Someone with local access to the system can trigger it. Administrator privileges are required. No user action is required. No special conditions are required; it is repeatable.
Fixed version: F5 BIG-IQ Hotfix-BIG-IQ-8.3.0.0.16.118-ENG.iso.

Low priority for now. Upgrade to F5 BIG-IQ Hotfix-BIG-IQ-8.3.0.0.16.118-ENG.iso or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

BIG-IP or BIG-IQ Resource Administrators and Certificate Managers who have access to the secure copy (scp) utility but do not have access to Advanced shell (bash) can execute arbitrary commands with a specially crafted command string. This vulnerability is due to an incomplete fix for CVE-2020-5873. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated
