During internal Axis Security Development Model (ASDM) threat-modelling, a flaw was found in the protection for device tampering (commonly known as Secure Boot) in AXIS OS making it vulnerable to a sophisticated attack to bypass this protection. To Axis' knowledge, there are no known exploits of the vulnerability at this time. Axis has released patched AXIS OS versions for the highlighted flaw. Please refer to the Axis security advisory for more information and solution.

CVE-2023-20101 is a critical vulnerability in Cisco Emergency Responder version 12.5(1)SU4 that involves hard-coded root credentials. An unauthenticated remote attacker can exploit this flaw to log in as root using static, unchangeable credentials embedded in the system. This allows full control over the affected device, enabling arbitrary command execution with root privileges. The vulnerability stems from development-only static credentials that were never removed or disabled in production releases. The CVSS score is 9.8, reflecting the high impact and ease of exploitation without authentication or user interaction. Although no known exploits are currently reported in the wild, the risk is severe given the critical nature of the affected systems. Cisco Emergency Responder is widely used in enterprise telephony and emergency call management, making this vulnerability particularly impactful. European organizations relying on Cisco telephony infrastructure could face significant confidentiality, integrity, and availability risks if exploited.

An attacker can leverage this flaw to gradually erode available memory to the point where named crashes for lack of resources. Upon restart the attacker would have to begin again, but nevertheless there is the potential to deny service.
