Quick assessment

Affected
SODOLA SL902-SWTGW124AS
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

SODOLA SL902-SWTGW124AS 版本低于 200.2.12 的固件中存在一个缓冲区溢出漏洞，未认证的攻击者可通过在精心构造的 POST 请求的 Content-Type 头部中发送过大的边界值，触发该漏洞并导致拒绝服务（DoS）。攻击者可利用设备内置 HTTP 服务器的 multipart/form-data 边界解析器，致使设备完全无响应——在其自动恢复周期内，所有管理访问和流量转发均会中断。

Vulnerability Title
SODOLA SL902-SWTGW124AS Buffer Overflow DoS via Multipart Boundary Parser
Source: CVE Program / CVE List V5
Vulnerability 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.
