Buffer Copy without Checking Size of Input (CWE-120) in the Controller 6000 and Controller 7000 diagnostic web interface allows an authorised and authenticated operator to reboot the Controller, causing a Denial of Service. Gallagher recommend the diagnostic web page is not enabled (default is off) unless advised by Gallagher Technical support. This interface is intended only for diagnostic purposes. This issue affects: Controller 6000 and Controller 7000 9.10 prior to vCR9.10.240816a (distributed in 9.10.1530 (MR2)), 9.00 prior to vCR9.00.240816a (distributed in 9.00.2168 (MR4)), 8.90 prior to vCR8.90.240816a (distributed in 8.90.2155 (MR5)), 8.80 prior to vCR8.80.240816b (distributed in 8.80.1938 (MR6)), all versions of 8.70 and prior.
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
