BACKGROUND The 3Com OfficeConnect Wireless 11g Access Point provides users with access to network resources, the Internet, and e-mail at speeds up to 54 Mbps and at distances up to 100 meters (328 feet). More information about the product is available at http://www.3com.com/products/en_US/detail.jsp?tab=features &pathtype=purchase&sku=3CRWE454G72 II. DESCRIPTION Remote exploitation of an input validation vulnerability in 3Com Corp.'s OfficeConnect Wireless 11g Access Point allows attackers to glean sensitive router information. The 3Com OfficeConnect Wireless 11g Access Point (AP) provides an administrative interface via a web server accessible on port 80. This interface is exposed by default on the internal ethernet interface and the wireless interface, and it is also possible to expose it on the external ethernet interface. The problem specifically exists due to insufficient privilege checks when accessing various URLs without going through the formal logon process. An unauthenticated attacker can glean sensitive information from the device via the following URLs: /main/config.bin /main/profile.wlp?PN=ggg /main/event.logs These URLs will expose the administrative username and password in clear text, the WEP key and SSID, and the router log file respectively. III. ANALYSIS Successful exploitation allows remote attackers to glean sensitive router information, allowing the attacker to gain full control of the device. Compromise of the Access Point (AP) allows an attacker to potentially redirect traffic, access nodes behind the AP that are otherwise unaddressable and potentially monitor traffic from a remote location. This can lead to further compromise of other computers. IV. DETECTION It has been reported that firmware version 1.00.08 shipped on the 3Com OfficeConnect Wireless 11g Access Point is vulnerable. It is suspected that earlier versions are also vulnerable. V. WORKAROUND iDEFENSE is currently unaware of any workarounds for this issue. VI. VENDOR RESPONSE Firmware version 1.03.07A for 3CRWE454G72 has been released to addresses the vulnerability. http://www.3com.com/products/en_US/result.jsp?selected=6&sort=effdt &order=desc&sku=3CRWE454G72 VII. CVE INFORMATION The Common Vulnerabilities and Exposures (CVE) project has assigned the names CAN-2005-0112 to these issues. This is a candidate for inclusion in the CVE list (http://cve.mitre.org), which standardizes names for security problems. VIII.
