- Severity: CVSS 8.7 (High), CNA
- Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N
- CISA SSVC: exploitation=poc, automatable=yes, technicalImpact=partial
- Known exploited (CISA KEV): no
- Published: 2026-10-15 · Updated: 2026-10-27

## Affected

- SODOLA SL902-SWTGW124AS: through 200.2.12

## Description

SODOLA SL902-SWTGW124AS firmware before 200.2.12 contains a buffer overflow vulnerability that allows unauthenticated remote attackers to cause a denial of service by sending an oversized boundary value in the Content-Type header of a crafted POST request. Attackers can exploit the embedded HTTP server's multipart/form-data boundary parser to cause the device to become fully unresponsive — dropping all management access and traffic forwarding during its self-recovery cycle.
