Dolibarr 23.0.4 before 24.0.1 ontains an authorization bypass vulnerability that allows unauthenticated attackers to read arbitrary files through the document storage endpoints by supplying a crafted hashp parameter value. Attackers can send a request with hashp=shared to skip token validation while satisfying the authorization condition in htdocs/document.php and htdocs/viewimage.php, gaining access to application logs, uploaded business documents, database backups containing password hashes, and files belonging to other multicompany entities.
AnalysisAI
Unauthenticated arbitrary file read in Dolibarr 23.0.4 through 24.0.0 allows remote attackers to exfiltrate sensitive data by exploiting a hardcoded bypass value in the document access endpoints. Supplying hashp=shared in requests to htdocs/document.php and htdocs/viewimage.php satisfies the authorization condition without a valid token, granting read access to application logs, uploaded business documents, database backups containing password hashes, and files across multicompany tenant boundaries. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The target Dolibarr instance must be running version 23.0.4 through 24.0.0 and must be network-accessible to the attacker - no authentication, no special privileges, and no non-default configuration required. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N) scores 8.7 and accurately reflects the severity: network-reachable, zero prerequisites, no user interaction, and high confidentiality impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade to Dolibarr 24.0.1 or later, which contains the fix at commit cd05688dbed8a4af6eef32faf4fc1e823a37bce9 (https://github.com/Dolibarr/dolibarr/releases/tag/24.0.1). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all Dolibarr instances to identify those running versions 23.0.4-24.0.0 and immediately restrict external network access to htdocs/document.php and htdocs/viewimage.php via firewall or WAF rules blocking the hashp parameter. …
