EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

source: https://www.securityfocus.com/bid/2048/info The Phone Book Service is an optional component that ships with the NT 4 Option Pack and Windows 2000. It is not installed by default. A buffer overflow vulnerability was discovered in the URL processing routines of the Phone Book Service requests on IIS 4 and IIS 5. If exploited, this vulnerability allows an attacker to execute arbitrary code and obtain a remote command shell with those privileges of the IUSR_machinename account (IIS 4) or the IWAM_machinename account (IIS 5). The Phone Book server services requests using the Internet Information Services 5.0 with URIs such as http://hostname/pbserver/ According to Microsoft's documentation a DLL (PBSERVER.DLL) is exported and the services can be used making requests with the following format: http://hostname/pbserver/pbserver.dll?osarch=&ostype=&osver=&cmver=&lcid=&pb ver=&pb= In the DLL checks the total lenght to ensure that request does not exceed 1024 bytes, however it is possible to overflow a local variable of fixed length in the DLL by sending a request with the following form: GET /pbserver/pbserver.dll?&&&&&&pb=AAAAAA... (less than 980 chars) HTTP/1.0\n\n The result is an exception reported in the Event log with source WAM like the following: The HTTP server encountered an unhandled exception while processing the ISAPI Application ' + 0x41414143 + 0x41414139 pbserver!HttpExtensionProc + 0x1C wam!DllGetClassObject + 0x808 RPCRT4!NdrServerInitialize + 0x4DB RPCRT4!NdrStubCall2 + 0x586 RPCRT4!CStdStubBuffer_Invoke + 0xC1 ole32!StgGetIFillLockBytesOnFile + 0x116EC ole32!StgGetIFillLockBytesOnFile + 0x12415 ole32!DcomChannelSetHResult + 0xDF0 ole32!DcomChannelSetHResult + 0xD35 ole32!StgGetIFillLockBytesOnFile + 0x122AD ole32!StgGetIFillLockBytesOnFile + 0x1210A ole32!StgGetIFillLockBytesOnFile + 0x11E22 RPCRT4!NdrServerInitialize + 0x745 RPCRT4!NdrServerInitialize + 0x652 RPCRT4!NdrServerInitialize + 0x578 RPCRT4!RpcSmDestroyClientContext + 0x9E RPCRT4!NdrConformantArrayFree + 0x8A5 RPCRT4!NdrConformantArrayFree + 0x3FC RPCRT4!RpcBindingSetOption + 0x395 RPCRT4!RpcBindingSetOption + 0x18E RPCRT4!RpcBindingSetOption + 0x4F8 KERNEL32!CreateFileA + 0x11B For additional information specific to this message please visit the Microsoft Online Support site located at: http://www.microsoft.com/contentredirect.asp. By sending a carefully crafted HTTP request an attacker can bypass the total length check and overflow a local variable in PBSERVER.DLL allowing the execution of arbitrary code as user GUEST on the vulnerable machine.
