HIGH 7.8

DescriptionNVD

An authenticated shell command injection issue has been discovered in Raisecom ISCOM HT803G-U, HT803G-W, HT803G-1GE, and HT803G GPON products with the firmware version ISCOMHT803G-U_2.0.0_140521_R4.1.47.002 or below. The value of the fmgpon_loid parameter is used in a system call inside the boa binary. Because there is no user input validation, this leads to authenticated code execution on the device.

AnalysisAI

An authenticated shell command injection issue has been discovered in Raisecom ISCOM HT803G-U, HT803G-W, HT803G-1GE, and HT803G GPON products with the firmware version. Rated high severity (CVSS 7.8), this vulnerability is low attack complexity. Public exploit code available and no vendor patch available.

Technical ContextAI

This vulnerability is classified as OS Command Injection (CWE-78), which allows attackers to execute arbitrary operating system commands on the host. An authenticated shell command injection issue has been discovered in Raisecom ISCOM HT803G-U, HT803G-W, HT803G-1GE, and HT803G GPON products with the firmware version ISCOMHT803G-U_2.0.0_140521_R4.1.47.002 or below. The value of the fmgpon_loid parameter is used in a system call inside the boa binary. Because there is no user input validation, this leads to authenticated code execution on the device. Affected products include: Raisecom Iscom Ht803G-U Firmware, Raisecom Iscom Ht803G-W Firmware, Raisecom Iscom Ht803G-1Ge Firmware, Raisecom Iscom Ht803G Gpon Firmware.

RemediationAI

No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Avoid passing user input to shell commands. Use language-specific APIs instead of shell execution. Apply strict input validation with allowlists.
