CVE-2024-4259: Sensetive Data Exposure in SAMPAS's AKOS
Missing Authorization vulnerability in SAMPAŞ Holding AKOS (AkosCepVatandasService), SAMPAŞ Holding AKOS (TahsilatService) allows Collect Data as Provided by Users.
This issue affects AKOS (AkosCepVatandasService): before V2.0; AKOS (TahsilatService): before V1.0.7.
Security readout for executives and security teams
Plain-English summary
AKOS service endpoints may expose user-provided data because authorization checks are missing. Organizations using affected SAMPAŞ Holding AKOS components should treat this as a privacy and trust risk, especially where citizen or payment-service data is processed.
Executive priority
Prioritize remediation for internet-facing AKOS deployments or systems handling citizen or payment-related data. This is not rated critical, but unauthenticated data exposure can create regulatory, reputational, and operational consequences.
Technical view
CVE-2024-4259 is a CWE-862 missing authorization issue in AKOS AkosCepVatandasService before V2.0 and TahsilatService before V1.0.7. The CVSS 4.0 score is 6.9, with network attack vector, low complexity, no privileges, and no user interaction required.
Likely exposure
Exposure is limited to organizations running the named SAMPAŞ Holding AKOS services below the stated versions. The sources do not identify cloud, appliance, or default deployment details.
Exploitation context
The source bundle does not cite active exploitation, and the CVE is not marked as CISA KEV. The scoring indicates remote unauthenticated reachability, but no public exploit details are provided.
Researcher notes
Evidence is sparse beyond the CVE record and government advisory references. Avoid assuming specific data fields, exploit maturity, or patch mechanics beyond the stated affected versions and missing authorization classification.
Mitigation direction
Identify whether AKOS AkosCepVatandasService or TahsilatService is deployed.
Upgrade AkosCepVatandasService to V2.0 or later where applicable.
Upgrade TahsilatService to V1.0.7 or later where applicable.
Review SAMPAŞ Holding or Turkish government guidance for any deployment-specific instructions.
Restrict external access to affected services until authorization behavior is confirmed.
Validation and detection
Inventory AKOS service names and versions across production and staging environments.
Confirm exposed endpoints require authorization before returning user-provided data.
Review access logs for unusual unauthenticated data collection patterns.
Check vendor or government advisories for corrected version confirmation.
Document affected systems, remediation dates, and residual compensating controls.

CWE-862: Authorization and privilege behavior lookup
Authorization weaknesses can support privilege escalation and valid-account review, depending on exploit path. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.
