CVE-2023-21406


Ariel Harush and Roy Hodir from OTORIO have found a flaw in the AXIS A1001 when communicating over OSDP. A heap-based buffer overflow was found in the pacsiod process which is handling the OSDP communication allowing to write outside of the allocated buffer. By appending invalid data to an OSDP message it was possible to write data beyond the heap allocated buffer. The data written outside the buffer could be used to execute arbitrary code.  lease refer to the Axis security advisory for more information, mitigation and affected products and software versions.


Security Impact Summary

This vulnerability carries a HIGH severity rating with a CVSS v3.1 score of 7.1, indicating it requires adjacent network access but requires specific conditions to be met without requiring user interaction and does not require pre-existing privileges . The vulnerability impacts limited data confidentiality, integrity (unauthorized modifications), and availability (service disruption) for affected systems. Impacting 2 products from axis, from axis organizations running these solutions should prioritize assessment and patching.

Historical Context

Reported in 2023, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

How SecUtils Interprets This CVE

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For axis's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
