An unauthenticated remote attacker can inject malicious input into the ModbusServer application because it does not validate the input it fetches… (CVE-2026-44092)
CVE-2026-44092 is a vulnerability in the ModbusServer application where unauthenticated remote attackers can inject malicious input due to lack of input validation from MQTT sources. This flaw can lead to loss of data integrity and availability within the affected application.
AI Analysis
Technical Summary
The ModbusServer application fails to validate input fetched from MQTT, allowing an unauthenticated remote attacker to inject malicious data. This vulnerability is categorized under CWE-93 (Improper Neutralization of CRLF Sequences in HTTP Headers), indicating potential injection issues. The impact includes potential integrity and availability loss of the application. There is no information about affected versions or available patches. The vulnerability is not related to a cloud service, and no known exploits are reported in the wild.
Potential Impact
An attacker can remotely inject malicious input without authentication, potentially compromising the integrity and availability of the ModbusServer application. This could disrupt normal operations or corrupt data handled by the application.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the ModbusServer application and monitor for unusual activity related to MQTT input. Implement network-level controls to limit exposure to untrusted sources if possible.
