Cylance revealed vulnerability within the InnGate product line in a security advisory on Thursday. The vulnerability has been classified as CVE-2015-0932 and it occurred due to incorrect sync configuration in the firmware of certain InnGate HSIA models, which enabled external systems to obtain unrestricted read and write file access. As a result, an unauthorized user could gain full access to hotel Wi-Fi systems.
Cylance security expert Brian Wallace reported:”When an attacker gains full read and write access to a Linux file system, it’s trivial to then turn that into remote code execution. The attacker could upload a backdoored version of nearly any executable on the system and then gain execution control, or simply add an additional user with root level access and a password known to the attacker. Once full file system access is obtained, the endpoint is at the mercy of the attacker.”
ANTLabs affirmed the existence of the vulnerability in a blogpost. The products affected are mentioned below:
- IG 3100 model 3100, model 3101
- InnGate 3.00 E-Series, 3.01 E-Series, 3.02 E-Series, 3.10 E-Series
- InnGate 3.01 G-Series, 3.10 G-Series
Hotel networks have always been a lucrative source for cyberattackers looking to steal valuable data and afflict victims with malware based on the quick succession of victims connecting to Wi-Fi networks offered at hotels.
Last year Kaspersky Labs disclosed an advanced persistent threat (APT) campaign that dubbed DarkHotel. The campaign had been designed to trap incautious business travelers in Asia. They used malware skulking on hotel networks to entice them into downloading and installing trapdoors disguised as ‘welcome’ packages. In return, the victim’s PC came down with spyware.
