The vulnerability is a classic SUID root weakness that can give the attacker full control of the device and its firmware. Precise exploitation possibilities include arbitrary code execution as root, manipulation of system configuration, or persistence via rogue binaries.", "risk_and_exploitability": "The base CVSS score of 8.6 indicates a high\u2011severity flaw. EPSS is reported as less than 1%; thus, while the vulnerability is currently low probability for exploitation, it remains a serious risk because local attackers\u2014such as maintenance staff or an attacker who first compromises the device remotely\u2014could use the SUID binary via PATH hijacking, symlink abuse, or shared object hijacking. The flaw is not listed in CISA\u2019s KEV catalog, but its high CVSS and root escalations warrant immediate attention. The most likely attack vector is a local actor who has read\u2011write access to the user\u2019s home directory or can alter PATH entries to inject malicious programs that the SUID binary will subsequently execute."}}}}, "created": "2026-03-06T15:18:05.004296+00:00", "updated": "2026-04-18T10:00:10.348914+00:00", "vendors": ["international_datacasting_corporation", "international_datacasting_corporation$PRODUCT$sfx2100_satellite_receiver"]}
