Monthly
Stack-based buffer overflow in the D-Link DIR-825M 1.1.8 LTE Module Firmware Upgrade handler allows low-privileged remote attackers to achieve remote code execution by supplying an oversized fota_url argument to /boafrm/formLtefotaUpgradeFibocom. The CVSS 4.0 vector scores this at 8.6 with subsequent-system impact (SC:H/SI:H/SA:H), reflecting the potential to compromise the attached Fibocom LTE module as well as the primary router. A public proof-of-concept exploit is available on GitHub, significantly lowering the bar for exploitation; no public patch has been identified at time of analysis.
