Successful exploitation of this vulnerability could allow an attacker to execute arbitrary code.
The following versions of AXIS A1001, a network door controller, are affected:
3.2.1 HEAP-BASED BUFFER OVERFLOW CWE-122
A heap-based buffer overflow vulnerability exists in the AXIS 1001 versions 1.65.4 and prior. When communicating over the Open Supervised Device Protocol (OSDP), the pacsiod process that handles the OSDP communication allows for writing outside of the allocated buffer. By appending invalid data to an OSDP message, it is possible to write data beyond the heap allocated buffer. The data written outside the buffer could allow an attacker to execute arbitrary code.
CVE-2023-21406 has been assigned to this vulnerability. A CVSS v3 base score of 7.1 has been assigned; the CVSS vector string is (AV:A/AC:H/PR:N/UI:N/S:U/C:L/I:H/A:H).
Ariel Harush and Roy Hodir of OTORIO reported this vulnerability to AXIS Communications.
