## Affected

- Shenzhen Hongyavision Technology Co., Ltd. (Sodola Networks) SODOLA SL902-SWTGW124AS: through 200.1.20

## Description

SODOLA SL902-SWTGW124AS firmware versions through 200.1.20 contain a weak session identifier generation vulnerability that allows attackers to forge authenticated sessions by computing predictable MD5-based cookies.
