• → CVE-2021-22803 is exploitable via crafted network messages sent to the IGSS Data Collector process (dc.exe); monitor for unexpected inbound network connections to dc.exe and arbitrary file write activity in its working directories. ↗

• · No authentication is required to exploit this vulnerability (PR:N, UI:N); the attack is network-reachable with low complexity, making any internet-exposed dc.exe instance immediately at risk. ↗
• · Affected versions are IGSS Data Collector (dc.exe) v15.0.0.21243 and prior; v15.0.0.21244 contains the fix. Verify the running version before assuming patched status. ↗
• · No known public exploits were reported at time of advisory publication, but CVSS 9.8 and no-auth network vector make this high-priority for patching. ↗
