OpenText Documentum Content Server before 23.2 has a flaw that allows for privilege escalation from a non-privileged Documentum user to root. The software comes prepackaged with a root owned SUID binary dm_secure_writer. The binary has security controls in place preventing creation of a file in a non-owned directory, or as the root user. However, these controls can be carefully bypassed to allow for an arbitrary file write as root.

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 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 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 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 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 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.

EMC Documentum Content Server before 7.1P20 and 7.2.x before 7.2P04 does not properly verify authorization for dm_job object access, which allows remote authenticated users to obtain superuser privileges via crafted object operations. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-4626.

EMC Documentum Content Server before 6.7SP1 P32, 6.7SP2 before P25, 7.0 before P19, 7.1 before P16, and 7.2 before P02 does not properly check authorization for subgroups of privileged groups, which allows remote authenticated sysadmins to gain super-user privileges, and bypass intended restrictions on data access and server actions, via unspecified vectors. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-4622.
