Opentext : Security Vulnerabilities, CVEs, Published In 2017

OpenText Documentum Content Server (formerly EMC Documentum Content Server) through 7.3 contains the following design gap, which allows an authenticated user to gain superuser privileges: Content Server allows uploading content using batches (TAR archives). When unpacking TAR archives, Content Server fails to verify the contents of an archive, which causes a path traversal vulnerability via symlinks. Because some files on the Content Server filesystem are security-sensitive, this leads to privilege escalation.

OpenText Documentum Content Server (formerly EMC Documentum Content Server) through 7.3 contains the following design gap, which allows authenticated users to download arbitrary content files regardless of the attacker's repository permissions: When an authenticated user uploads content to the repository, he performs the following steps: (1) calls the START_PUSH RPC-command; (2) uploads the file to the content server; (3) calls the END_PUSH_V2 RPC-command (here, Content Server returns a DATA_TICKET integer, intended to identify the location of the uploaded file on the Content Server filesystem); (4) creates a dmr_content object in the repository, which has a value of data_ticket equal to the value of DATA_TICKET returned at the end of END_PUSH_V2 call. As the result of this design, any authenticated user may create his own dmr_content object, pointing to already existing content in the Content Server filesystem.

OpenText Documentum Content Server (formerly EMC Documentum Content Server) through 7.3 contains the following design gap, which allows an authenticated user to gain superuser privileges: Content Server stores information about uploaded files in dmr_content objects, which are queryable and "editable" (before release 7.2P02, any authenticated user was able to edit dmr_content objects; now any authenticated user may delete a dmr_content object and then create a new one with the old identifier) by authenticated users; this allows any authenticated user to replace the content of security-sensitive dmr_content objects (for example, dmr_content related to dm_method objects) and gain superuser privileges.

OpenText Documentum Content Server (formerly EMC Documentum Content Server) through 7.3 does not properly validate the input of the PUT_FILE RPC-command, which allows any authenticated user to hijack an arbitrary file from the Content Server filesystem; because some files on the Content Server filesystem are security-sensitive, this leads to privilege escalation.

OpenText Document Sciences xPression (formerly EMC Document Sciences xPression) v4.5SP1 Patch 13 (older versions might be affected as well) is prone to an XML External Entity vulnerability: /xFramework/services/QuickDoc.QuickDocHttpSoap11Endpoint/. An unauthenticated user is able to read directory listings or system files, or cause SSRF or Denial of Service.

OpenText Document Sciences xPression (formerly EMC Document Sciences xPression) v4.5SP1 Patch 13 (older versions might be affected as well) is prone to SQL Injection: /xAdmin/html/cm_doclist_view_uc.jsp, parameter: documentId. In order for this vulnerability to be exploited, an attacker must authenticate to the application first.

OpenText Document Sciences xPression (formerly EMC Document Sciences xPression) v4.5SP1 Patch 13 (older versions might be affected as well) is prone to SQL Injection: /xDashboard/html/jobhistory/downloadSupportFile.action, parameter: jobRunId. In order for this vulnerability to be exploited, an attacker must authenticate to the application first.

OpenText Document Sciences xPression (formerly EMC Document Sciences xPression) v4.5SP1 Patch 13 (older versions might be affected as well) is prone to Cross-Site Scripting: /xAdmin/html/Deployment (cat_id).

OpenText Document Sciences xPression (formerly EMC Document Sciences xPression) v4.5SP1 Patch 13 (older versions might be affected as well) is prone to Cross-Site Scripting: /xAdmin/html/XPressoDoc, parameter: categoryId.

OpenText Document Sciences xPression (formerly EMC Document Sciences xPression) v4.5SP1 Patch 13 (older versions might be affected as well) is prone to Arbitrary File Read: /xAdmin/html/cm_datasource_group_xsd.jsp, parameter: xsd_datasource_schema_file filename. In order for this vulnerability to be exploited, an attacker must authenticate to the application first.

Multiple XML external entity (XXE) vulnerabilities in the OpenText Documentum Webtop 6.8.0160.0073 allow remote authenticated users to list the contents of arbitrary directories, read arbitrary files, cause a denial of service, or, on Windows, obtain Documentum user hashes via a (1) crafted DTD, involving unspecified XML structures in a request to xda/com/documentum/ucf/server/transport/impl/GAIRConnector or crafted XML file in a MediaProfile file (2) import or (3) check in.

Multiple XML external entity (XXE) vulnerabilities in the OpenText Documentum Administrator 7.2.0180.0055 allow remote authenticated users to list the contents of arbitrary directories, read arbitrary files, cause a denial of service, or, on Windows, obtain Documentum user hashes via a (1) crafted DTD, involving unspecified XML structures in a request to xda/com/documentum/ucf/server/transport/impl/GAIRConnector or crafted XML file in a MediaProfile file (2) import or (3) check in.

Multiple open redirect vulnerabilities in OpenText Documentum Webtop 6.8.0160.0073 allow remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via a (1) URL in the startat parameter to xda/help/en/default.htm or (2) /%09/ (slash encoded horizontal tab slash) followed by a domain in the redirectUrl parameter to xda/component/virtuallinkconnect.

Multiple open redirect vulnerabilities in OpenText Documentum Administrator 7.2.0180.0055 allow remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via a (1) URL in the startat parameter to xda/help/en/default.htm or (2) /%09/ (slash encoded horizontal tab slash) followed by a domain in the redirectUrl parameter to xda/component/virtuallinkconnect.

Cross-site scripting (XSS) vulnerability in OpenText Tempo Box 10.0.3 allows remote attackers to inject arbitrary web script or HTML persistently via the name of an uploaded image.

OpenText Documentum Content Server has an inadequate protection mechanism against SQL injection, which allows remote authenticated users to execute arbitrary code with super-user privileges by leveraging the availability of the dm_bp_transition docbase method with a user-created dm_procedure object, as demonstrated by use of a backspace character in an injected string. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-2513.

OpenText Documentum Content Server allows superuser access via sys_obj_save or save of a crafted object, followed by an unauthorized "UPDATE dm_dbo.dm_user_s SET user_privileges=16" command, aka an "RPC save-commands" attack. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-4532.

OpenText Documentum D2 (formerly EMC Documentum D2) 4.x allows remote attackers to execute arbitrary commands via a crafted serialized Java object, related to the BeanShell (bsh) and Apache Commons Collections (ACC) libraries.

OpenText Documentum Content Server (formerly EMC Documentum Content Server) 7.3, when PostgreSQL Database is used and return_top_results_row_based config option is false, does not properly restrict DQL hints, which allows remote authenticated users to conduct DQL injection attacks and execute arbitrary DML or DDL commands via a crafted request. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-2520.
