**Name of the Vulnerable Software and Affected Versions** NETGEAR R6260 version 1.1.0.78 1.0.1 NETGEAR AC2100, AC2400, AC2600, D7000, R6020, R6080, R6120, R6220, R6230, R6350, R6330, R6700v2, R6800, R6850, R6900v2, R7200, R7350, R7400, R7450, WAC124 (affected versions not specified) **Description** This issue allows network-adjacent attackers to execute arbitrary code on affected installations of NETGEAR routers. Authentication is not required to exploit this issue. The specific flaw exists within the setupwizard.cgi page. A crafted SOAP request can trigger an overflow of a fixed-length stack-based buffer. An attacker can leverage this issue to execute code in the context of root. **Recommendations** For NETGEAR R6260 version 1.1.0.78 1.0.1, consider disabling access to the setupwizard.cgi page until a patch is available. For NETGEAR AC2100, AC2400, AC2600, D7000, R6020, R6080, R6120, R6220, R6230, R6350, R6330, R6700v2, R6800, R6850, R6900v2, R7200, R7350, R7400, R7450, WAC124, restrict access to the setupwizard.cgi page to minimize the risk of exploitation. As a temporary workaround, consider blocking crafted SOAP requests to the setupwizard.cgi page until a patch is available. At the moment, there is no information about a newer version that contains a fix for this issue.

Authentication is not required to exploit this issue. The specific flaw exists within the handling of SOAP requests, specifically when parsing the `SOAPAction` header, the process does not properly validate the length of user-supplied data prior to copying it to a fixed-length buffer. An attacker can leverage this issue to execute code in the context of root. **Recommendations** For NETGEAR R6260 version 1.1.0.78 1.0.1, consider disabling the `mini httpd` service until a patch is available. For NETGEAR AC2100, AC2400, AC2600, R6020, R6080, R6120, R6330, R6350, R6700v2, R6800, R6850, R6900v2, R7200, R7350, R7400, R7450, at the moment, there is no information about a newer version that contains a fix for this issue.

**Name of the Vulnerable Software and Affected Versions** NETGEAR R6700AX versions (affected versions not specified) NETGEAR R7800 versions (affected versions not specified) NETGEAR R8900 versions (affected versions not specified) NETGEAR R9000 versions (affected versions not specified) NETGEAR RAX10 versions (affected versions not specified) NETGEAR RAX120 versions (affected versions not specified) NETGEAR RAX120v2 versions (affected versions not specified) NETGEAR RAX70 versions (affected versions not specified) NETGEAR RAX78 versions (affected versions not specified) NETGEAR XR700 versions (affected versions not specified) **Description** The issue is related to a buffer overflow when parsing the `soap block table` file, allowing an attacker to execute arbitrary code on affected installations of NETGEAR routers. The flaw exists due to the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated data structure. An attacker can leverage this vulnerability to execute code in the context of root. No authentication is required to exploit this vulnerability. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
