Detailsinfo

A vulnerability has been found in H3C ERG3, ERG5 and XiaoBei (the affected version is unknown) and classified as critical. Affected by this vulnerability is an unknown code. The manipulation of the argument sessionid with an unknown input leads to a injection vulnerability. The CWE definition for the vulnerability is CWE-74. The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

A remote command execution (RCE) vulnerability was discovered in all H3C ERG3/ERG5 series routers and XiaoBei series routers, cloud gateways, and wireless access points (versions R0162P07, UAP700-WPT330-E2265, UAP672-WPT330-R2262, UAP662E-WPT330-R2262P03, WAP611-WPT330-R1348-OASIS, WAP662-WPT330-R2262, WAP662H-WPT330-R2262, USG300V2-WPT330-R2129, MSG300-WPT330-R1350, and MSG326-WPT330-R2129).
