|漏洞详情
xferwan.exe是CentennialDiscovery产品中的一个服务进程,该服务也被其他第三方厂商使用。XFERWAN组件在处理超长请求时存在缓冲区溢出漏洞,远程攻击者可能利用此漏洞控制服务器。XFERWAN组件没有正确地解析超长请求,在记录请求时,没有检查Filename字段的长度便将用户提供的数据拷贝到了栈中,这可能触发栈溢出,导致在系统上执行任意指令。以下日志函数的反汇编说明了这个漏洞:004047A0movcl,Filename[eax]004047A6mov[esp+eax+890h+ExistingFileName],cl004047ADinceax004047AEtestcl,cl004047B0jnzshortloc_4047A0

TPTI-07-10: Centennial Software XferWan.exe Stack Overflow Vulnerability

http://dvlabs.tippingpoint.com/advisory/TPTI-07-10

June  4, 2007

-- CVE ID:

CVE-2007-2514

-- Affected Vendor:

Centennial Software

-- Affected Products:

Symantec Discovery 6.5

-- TippingPoint(TM) IPS Customer Protection:

TippingPoint IPS customers have been protected against this

vulnerability since April  3, 2007 by Digital Vaccine protection

filter ID 5231. For further product information on the TippingPoint IPS:

http://www.tippingpoint.com

-- Vulnerability Details:

This vulnerability allows remote attackers to execute arbitrary code on

vulnerable installations of software utilizing Centennial Software

XferWan. Authentication is not required to exploit this vulnerability.

The specific flaw exists during the parsing of overly long requests to

the XferWAN process. When logging requests, user-supplied data is

copied to the stack resulting in an exploitable buffer overflow

condition. The following disassembly excerpt from the logging function

demonstrates the issue:

004047A0 mov cl, Filename[eax]

004047A6 mov [esp+eax+890h+ExistingFileName], cl

004047AD inc eax

004047AE test cl, cl

004047B0 jnz short loc_4047A0

A lack of sanity checking on the size of 'Filename' results in an

exploitable stack-based  buffer overflow vulnerability that can result

in a system compromise running under the context of the SYSTEM user.

-- Vendor Response:

Centennial has rectified an issue in the XFERWAN omponent of Centennial

Discovery which could be remotely exploited by malicious people to

compromise a system.

This issue only affects systems running non-secure communications,

which comprise a very small percentage of installations worldwide.

Customers can find instructions on how to identify if they are

susceptible to the vulnerability and correct, if necessary on the

Centennial Customer Support website.
