Vulnerability Note VU#930956

Multiple ANTlabs InnGate models allow unauthenticated read/write to filesystem

Original Release date: 26 Mar 2015 | Last revised: 26 Mar 2015


ANTlabs InnGate is a gateway device designed for operating corporate guest/visitor networks. Multiple models and firmware versions of the InnGate has been shown to allow read/write access to remote unauthenticated users via a misconfigured rsync instance.


CWE-276: Incorrect Default Permissions

The instance of rsync included with the InnGate firmware is incorrectly configured to allow the entire filesystem to be read/write without authentication. A remote unauthenticated attacker may read or modify any file on the device's filesystem. More details can be found in a blog post from Cylance, Inc.

Devices containing affected firmware include:

  • 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


A remote unauthenticated attacker may read or modify any file on the device's filesystem.


Update the firmware
According to the ANTlabs Security Advisory, a software update addressing this vulnerability has been released. Users are encouraged to upgrade affected devices' software as soon as possible. Affected users may contact ANTlabs Support (tech-support@antlabs.com) for more information or to obtain the software update.

If a firmware update is currently not possible, the following workaround may help mitigate this issue.

Block rsync

Administrators may block unrestricted access to the rsync TCP port 873 on the affected network.
