Unauthenticated remote command execution
Published Jul 14, 2025 · Updated Jul 14, 2025
OS command injection in HGiga iSherlock 4.5 and 5.5 allows remote attackers to execute arbitrary commands on the gateway server. HGiga ties the maillog package to a specially crafted malicious email, while neither HGiga nor TWCERT/CC discloses the vulnerable function, unsafe command-building operation, or smtp trigger. No authentication or user interaction is required, and TWCERT/CC reports that the flaw has been exploited.
