Multiple buffer overflows in the LGServer component of CA (Computer Associates) BrightStor ARCserve Backup for Laptops and Desktops r11.1 allow remote attackers to execute arbitrary code via crafted arguments to the (1) rxsAddNewUser, (2) rxsSetUserInfo, (3) rxsRenameUser, (4) rxsSetMessageLogSettings, (5) rxsExportData, (6) rxsSetServerOptions, (7) rxsRenameFile, (8) rxsACIManageSend, (9) rxsExportUser, (10) rxsImportUser, (11) rxsMoveUserData, (12) rxsUseLicenseIni, (13) rxsLicGetSiteId, (14) rxsGetLogFileNames, (15) rxsGetBackupLog, (16) rxsBackupComplete, (17) rxsSetDataProtectionSecurityData, (18) rxsSetDefaultConfigName, (19) rxsGetMessageLogSettings, (20) rxsHWDiskGetTotal, (21) rxsHWDiskGetFree, (22) rxsGetSubDirs, (23) rxsGetServerDBPathName, (24) rxsSetServerOptions, (25) rxsDeleteFile, (26) rxsACIManageSend, (27) rxcReadBackupSetList, (28) rxcWriteConfigInfo, (29) rxcSetAssetManagement, (30) rxcWriteFileListForRestore, (31) rxcReadSaveSetProfile, (32) rxcInitSaveSetProfile, (33) rxcAddSaveSetNextAppList, (34) rxcAddSaveSetNextFilesPathList, (35) rxcAddNextBackupSetIncWildCard, (36) rxcGetRevisions, (37) rxrAddMovedUser, (38) rxrSetClientVersion, or (39) rxsSetDataGrowthScheduleAndFilter commands.

The bug was discovered 06/04/2007. The weakness was disclosed 06/11/2007 by Sean Larsson with eEye (Website). The advisory is shared for download at research.eeye.com. The public release has been coordinated in cooperation with the vendor. This vulnerability was named CVE-2007-3216 since 06/14/2007. The attack needs to be initiated within the local network. No form of authentication is required for a successful exploitation. Technical details are unknown but a public exploit is available.

It is possible to download the exploit at saintcorporation.com. It is declared as highly functional. The vulnerability was handled as a non-public zero-day exploit for at least 7 days. During that time the estimated underground price was around $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 69317 (CA ARCserve Backup for Laptops and Desktops Server and CA Desktop Management Suite Multiple Remote Vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Windows and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 370648 (CA ARCserve Backup for Laptops and Desktops Server Multiple Security Vulnerabilities).

The best possible mitigation is suggested to be disabling the affected component. A possible mitigation has been published 4 months after the disclosure of the vulnerability. Attack attempts may be identified with Snort ID 12786. In this case the pattern rxsSetDataGrowthScheduleAndFilter is used for detection. Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 5676.

The vulnerability is also documented in the databases at X-Force (34805) and Tenable (69317). The entries 39039, 39038, 39037 and 39036 are pretty similar.
