Overview<\/strong><\/p>\n

In the constantly evolving landscape of cybersecurity, vulnerabilities are unearthed and addressed on a regular basis. This particular post dives into a critical vulnerability discovered in several Linksys range extender models, which could potentially trigger a stack-based buffer overflow. The exploit is a concern as it can be triggered remotely, and it opens up the possibility of system compromise<\/a> or data leakage. Moreover, the exploit is now public knowledge, hence increasing the urgency to address it. The vulnerability is designated<\/a> as CVE-2025-9361, and the severity of the issue is significant enough to warrant immediate attention and mitigation.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-9361
\nSeverity: High (CVSS Score: 8.8)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: System compromise or data<\/a> leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Linksys RE6250 | 1.0.013.001\/1.0.04.001\/1.0.04.002
\nLinksys RE6300 | 1.0.013.001\/1.0.04.001\/1.0.04.002
\nLinksys RE6350 | 1.0.013.001\/1.0.04.001\/1.0.04.002

\nLinksys RE7000 | 1.1.05.003
\nLinksys RE9000 | 1.2.07.001<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The exploit takes advantage of a buffer overflow vulnerability<\/a>. By manipulating the argument ‘ipRangeBlockRuleName\/scheduleIp\/ipRangeBlockRuleIpAddr’ in the ‘ipRangeBlockManageRule’ function of the ‘\/goform\/ipRangeBlockManageRule’ file, an attacker can cause a stack-based buffer overflow<\/a>. This overflow can lead to arbitrary code<\/a> execution or cause the system to crash, compromising the integrity of the device and potentially leading to data leakage.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Below is a conceptual example of how this vulnerability might be exploited:<\/p>\n

POST \/goform\/ipRangeBlockManageRule HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/x-www-form-urlencoded\nipRangeBlockRuleName=ANY_NAME&scheduleIp=ANY_IP&ipRangeBlockRuleIpAddr=ANY_IP_ADDRESS&overflow_data=LONG_STRING_TO_TRIGGER_OVERFLOW<\/code><\/pre>\n
In the above hypothetical example, the ‘overflow_data’ field is loaded with an excessively long string to trigger a buffer overflow<\/a>.
\nPlease note that this example is conceptual and should not be used to exploit real systems. It is provided for educational purposes to understand the nature of the vulnerability<\/a> and to facilitate its mitigation.<\/p>\n","protected":false},"excerpt":{"rendered":"
