Dolibarr before 24.0.0 contains a SQL injection vulnerability in the users REST API that allows authenticated attackers with user-read rights to extract sensitive data by splicing unsanitized filter parameters into SQL WHERE clauses without column restrictions. Attackers can perform binary search on numeric fields and LIKE prefix iteration on string fields to recover salary figures and password verifiers omitted from normal API responses, while raw database error messages in the same endpoint enable column name enumeration.

Dolibarr before 24.0.0 contains a broken object-level authorization vulnerability in the REST API third-party site account write routes that allows authenticated attackers with third-party creation rights to overwrite the WebPortal password of any company by bypassing per-object access checks that are only enforced on read routes. Attackers can replace the victim company's WebPortal password through the write endpoint, authenticate as that company to access its invoice data, and also obtain the victim's previous password verifier from the API response.

Dolibarr 21.0.0 before 24.0.0 contains an authorization bypass vulnerability caused by an inverted boolean condition in the private-project membership check within the clonetasks mass action handler in htdocs/core/actions_massactions.inc.php. Authenticated users with project creation permission but without access to a target private project can exploit the flawed !in_array() check to clone tasks into unauthorized private projects.

A weakness has been identified in Dolibarr up to 23.0.4. This affects an unknown part of the file htdocs/user/card.php of the component Account Handler. This manipulation of the argument ID causes improper authorization. The attack may be initiated remotely. The exploit has been made available to the public and could be used for attacks. Upgrading to version 24.0.0 is able to mitigate this issue. Patch name: b2a2c995537cb6282383b5e903cb5ffa29b823e6. The affected component should be upgraded.

A security flaw has been discovered in Dolibarr up to 23.0.3. Affected is an unknown function of the file htdocs/user/card.php of the component User Cloning. The manipulation of the argument ID results in ldap injection. It is possible to launch the attack remotely. The exploit has been released to the public and may be used for attacks. The patch is identified as 798e65356ede03c2812ab1a728f23fae34de5592. It is advisable to implement a patch to correct this issue.

Dolibarr through 23.0.3, fixed in commit 14db36e, contains a sql injection vulnerability that allows authenticated API users to exfiltrate arbitrary database contents by supplying malicious values to the sqlfilters query parameter in the setup dictionary and multicurrencies REST API endpoints. The affected endpoints in api_setup.class.php and api_multicurrencies.class.php validate sqlfilters only for balanced parentheses and rewrite matched triplets, allowing text placed outside the expected shape such as an appended UNION SELECT to be concatenated into the SQL WHERE clause unmodified, enabling retrieval of sensitive data including password hashes and API keys.
