CVE-2024-51983: CWE-1286 Improper Validation of Syntactic Correctness of Input in Brother Industries, Ltd HL-L8260CDN
CVE-2024-51983 is a high-severity vulnerability affecting the Brother Industries HL-L8260CDN printer. An unauthenticated attacker can connect to the device's Web Services feature on HTTP port 80 and send a WS-Scan SOAP request with an unexpected JobToken value. This causes the device to crash and reboot. The attacker can repeatedly trigger this crash, resulting in a denial of service condition. There is no confirmed patch or official remediation available at this time.
AI Analysis
Technical Summary
This vulnerability involves improper validation of the syntactic correctness of input (CWE-1286) in the Brother HL-L8260CDN printer's Web Services feature. Specifically, the device fails to properly validate the JobToken value in WS-Scan SOAP requests received unauthenticated over HTTP port 80. Sending an unexpected JobToken causes the device to crash and reboot, enabling repeated denial of service attacks. The CVSS 3.1 base score is 7.5, reflecting network attack vector, no privileges required, no user interaction, and high impact on availability.
Potential Impact
The vulnerability allows an unauthenticated remote attacker to cause a denial of service by crashing and rebooting the affected printer repeatedly. There is no impact on confidentiality or integrity reported. The device becomes unavailable during the reboot cycle, potentially disrupting printing services.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restricting access to the device's HTTP port 80 interface from untrusted networks may reduce exposure. Monitor for updates from Brother Industries regarding an official fix or mitigation.
