CVE-2024-44775: n/a
kmqtt v0.2.7 is vulnerable to Denial of Service (DoS) due to a Null Pointer Exception. A remote attacker can cause the broker to crash by sending a specially crafted MQTT CONNECT packet that triggers an unhandled null reference, leading to an immediate process termination.
AI Analysis
Technical Summary
CVE-2024-44775 describes a denial of service vulnerability in kmqtt v0.2.7 caused by an unhandled null pointer exception. A remote attacker can exploit this by sending a malicious MQTT CONNECT packet that triggers the null reference, causing the broker to crash. The vulnerability is identified as CWE-444 (Improper Resource Shutdown or Release). The CVSS 3.1 base score is 7.5, reflecting high severity with network attack vector, low attack complexity, no privileges required, no user interaction, and impact limited to availability.
Potential Impact
Successful exploitation leads to a denial of service condition by crashing the kmqtt broker process, resulting in loss of availability. There is no reported impact on confidentiality or integrity. No known exploits are currently reported in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider implementing network-level protections to restrict access to the MQTT broker from untrusted sources to reduce exposure.
