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

The cybersecurity world is faced with another serious vulnerability, this time affecting a wide range of Linksys products. The vulnerability, tracked as CVE-2025-9482, is a critical flaw that can potentially compromise the system or cause data leakage. Affecting various versions of Linksys RE6250, RE6300, RE6350, RE6500, RE7000, and RE9000, the vulnerability has far-reaching effects on both businesses<\/a> and individual users who rely on these devices. The gravity of the situation is compounded by the fact that the exploit has been made public, potentially becoming a tool for cybercriminals.<\/p>\n

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

CVE ID: CVE-2025-9482
\nSeverity: Critical (8.8 CVSS Score)
\nAttack Vector: Remote
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: System compromise<\/a> or data leakage<\/p>\n

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

Product | Affected Versions<\/p>\n

Linksys RE6250 | 1.0.013.001
\nLinksys RE6300 | 1.0.04.001
\nLinksys RE6350 | 1.0.04.002
\nLinksys RE6500 | 1.1.05.003
\nLinksys RE7000 | 1.2.07.001
\nLinksys RE9000 | 1.2.07.001<\/p>\n

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

The vulnerability resides in the function portRangeForwardAdd of the file<\/a> \/goform\/portRangeForwardAdd. By manipulating the argument ruleName\/schedule\/inboundFilter\/TCPPorts\/UDPPorts, an attacker can cause a stack-based buffer overflow<\/a>. A buffer overflow<\/a> occurs when more data is written to a buffer than it can handle, causing the excess data to overflow into adjacent memory spaces. This can result in erratic program behavior, including memory access errors, incorrect results, program termination, or a breach of system security<\/a>.<\/p>\n

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

The following conceptual example illustrates how an attacker might exploit this vulnerability<\/a>:<\/p>\n

POST \/goform\/portRangeForwardAdd HTTP\/1.1\nHost: target.router.com\nContent-Type: application\/x-www-form-urlencoded\nruleName=overflown_data&schedule=any&inboundFilter=allow&TCPPorts=all&UDPPorts=all<\/code><\/pre>\n
In this example, the “overflown_data” is a large data string that causes the buffer overflow<\/a>. It’s important to note that this is a generalized example, and the actual exploit may be more complex.<\/p>\n","protected":false},"excerpt":{"rendered":"
