Vulnerability Details : CVE-2021-23851
A specially crafted TCP/IP packet may cause the camera recovery image web interface to crash. It may also cause a buffer overflow which could enable remote code execution. The recovery image can only be booted with administrative rights or with physical access to the camera and allows the upload of a new firmware in case of a damaged firmware.

CWE ids for CVE-2021-23851
-
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.Assigned by: nvd@nist.gov (Primary)
-
A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).Assigned by: psirt@bosch.com (Secondary)
