Vulnerability Disclosure Timeline: ================================== 2011-03-03: Vendor Notification 2011-04-19: Vendor Notification 2011-**-**: Vendor Response/Feedback 2011-**-**: Vendor Fix/Patch 2011-09-24: Public or Non-Public Disclosure Discovery Status: ================= Published Affected Product(s): ==================== UPEK - AuthenTec Product: Protector Suite QL 5.x & 2011 Q/3 Exploitation Technique: ======================= Local Severity Level: =============== High Technical Details & Description: ================================ A Buffer Overflow vulnerability is detected on the UPEK Protector Suite QL v5.x & version 2011 in combination with the EikonTouch USB peripheral. The vulnerability allows an local attacker to crash the EikonTouch USB peripheral device driver/software via local buffer overflow. The bug is located on the profile import module of the software when processing special crafted (manipualted) .vtp profile files. Vulnerable Module(s): [+] .VTP FILE - USERNAME Note: After the software crash the driver device of the fingerprinter crashs too. All control center functions are unavailable. --- Error Report 5.8er reproduce BOF --- EventType=BEX EventTime=129154019775611031 ReportType=2 Consent=1 UploadTime=129154019779511038 ReportIdentifier=cb14ade6-44d8-11df-9c98-9d81288f21db IntegratorReportIdentifier=cb14ade5-44d8-11df-9c98-9d81288f21db Response.BucketId=14960377 Response.BucketTable=4 Response.type=4 Sig[0].Name=Anwendungsname Sig[0].Value=upeksvr.exe Sig[1].Name=Anwendungsversion Sig[1].Value=5.8.2.4325 Sig[2].Name=Anwendungszeitstempel Sig[2].Value=48175c90 Sig[3].Name=Fehlermodulname Sig[3].Value=ntdll.dll Sig[4].Name=Fehlermodulversion Sig[4].Value=6.1.7600.16385 Sig[5].Name=Fehlermodulzeitstempel Sig[5].Value=4a5be02b Sig[6].Name=Ausnahmecode Sig[6].Value=c0000005 Sig[7].Name=Ausnahmeoffset Sig[7].Value=000000000004d174 DynamicSig[1].Name=Betriebsystemversion DynamicSig[1].Value=6.1.7600.2.0.0.768.3 DynamicSig[2].Name=Gebietsschema-ID DynamicSig[2].Value=1031 DynamicSig[22].Name=Zusatzinformation 1 DynamicSig[22].Value=f9a3 DynamicSig[23].Name=Zusatzinformation 2 DynamicSig[23].Value=f9a3d38cc4ed016f76897544c9f701e2 DynamicSig[24].Name=Zusatzinformation 3 DynamicSig[24].Value=6aaa DynamicSig[25].Name=Zusatzinformation 4 DynamicSig[25].Value=6aaa6991d936522896eee79c4369bf53 UI[2]=C://Program Files//Protector Suite QL//upeksvr.exe UI[3]=upeksvr.exe funktioniert nicht mehr UI[4]=Windows kann online nach einer Lösung für das Problem suchen.
