Network-accessible web wizard requires low privilege (import permission only); scope is unchanged as impact is confined to the application's own database; no availability impact from read and targeted-write exploitation.

DescriptionCVE.org

Dolibarr before 24.0.0 contains a SQL injection in its CSV and XLSX import wizard. The wizard reads its update keys with GETPOST('updatekeys', 'array') in htdocs/imports/import.php, which applies only the generic alphanohtml filter: that strips HTML but leaves SQL keywords, comment markers, parentheses, spaces and quotes intact. import_insert() in htdocs/core/modules/import/import_csv.modules.php then iterates the submitted values and builds a filter with $where[] = $key.' = '.$data[$key], having first applied preg_replace('/^.*\./i', '', $key), an alias strip that does nothing to a value containing no dot. The assembled string is executed through $this->db->query(). The injected SELECT resolves the row id that the import then assigns to $lastinsertid, which becomes the WHERE target of a subsequent UPDATE, so a UNION SELECT returning an attacker-chosen integer both exfiltrates arbitrary table content and redirects which row the import overwrites; for category link tables the raw filter array is spliced into that UPDATE directly. The interface offers a fixed list of legitimate column codes but the server never checks the submitted values against it. A user holding the import permission can exploit this. Release 23.0.4 does not carry the fix; the allow-list test was added in 24.0.0.

AnalysisAI

SQL injection in Dolibarr's CSV and XLSX import wizard (all versions before 24.0.0, including the most recent 23.0.4 stable release) allows an authenticated user holding the import permission to inject arbitrary SQL through the unsanitized updatekeys POST parameter. A crafted UNION SELECT payload simultaneously exfiltrates content from any database table the application account can read and hijacks the WHERE clause of the subsequent UPDATE to redirect which row is overwritten; for category link tables the raw filter array is spliced directly into UPDATE statements. …

Attack ChainAIDerived

Hypothetical attack flow derived from CVE metadata

Access
Obtain Dolibarr account with import permission
Delivery
Craft HTTP POST with UNION SELECT payload in updatekeys array
Exploit
Submit request to htdocs/imports/import.php
Execution
Server executes injected SQL in unsanitized WHERE clause
Persist
UNION SELECT leaks arbitrary table content
Impact
Attacker-controlled integer hijacks subsequent UPDATE target row

Vulnerability AssessmentAI

Exploitation Exploitation requires an authenticated Dolibarr session with the import permission explicitly granted to the user account; unauthenticated network access alone is insufficient to reach the vulnerable code path. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 score of 8.6 (AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N) accurately captures the core threat profile: the import wizard is network-accessible, the injection requires no unusual complexity, and the combined confidentiality and integrity impact is high. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker who controls or has compromised a Dolibarr account with the import permission initiates a CSV import and submits a crafted updatekeys POST array where one entry is a UNION SELECT payload rather than a legitimate column code. The server processes the payload without allowlist validation, executes the injected SQL against the database, and returns an attacker-chosen integer as the resolved row identifier - redirecting the subsequent UPDATE to an arbitrary row while the UNION SELECT result leaks content from any table the database user can access. …
Remediation Upgrade Dolibarr to version 24.0.0 or later - this is the only confirmed fixed release. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, identify all Dolibarr instances running versions before 24.0.0 (particularly 23.0.4 stable release) and audit which users hold import permissions to assess exposure. …
