CVE-2025-13129 Overview
CVE-2025-13129 is a medium-severity vulnerability affecting Seneka Software Hardware Information Technology Trade Contracting and Industry Ltd. Co.'s Onaylarım application. This Improper Enforcement of Behavioral Workflow vulnerability (CWE-841) allows attackers to misuse application functionality through workflow bypass techniques.
The vulnerability exists in versions 25.09.26.01 through 18112025 of the Onaylarım software. Due to improper enforcement of behavioral workflows, authenticated attackers can exploit functionality misuse vectors to manipulate application behavior in unintended ways.
Critical Impact
Authenticated attackers with network access can bypass workflow enforcement controls to misuse application functionality, potentially compromising data integrity.

Technical Details for CVE-2025-13129
Vulnerability Analysis
This vulnerability is classified under CWE-841: Improper Enforcement of Behavioral Workflow. The Onaylarım application fails to properly enforce expected behavioral workflows, allowing attackers to perform actions outside the intended sequence or bypass required authorization steps.
The vulnerability has been assigned a CVSS v3.1 score of 4.3 (Medium severity) with the vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N. This indicates:
- Attack Vector (AV): Network - Exploitable remotely without physical access
- Attack Complexity (AC): Low - No specialized conditions required
- Privileges Required (PR): Low - Attacker needs basic authentication
- User Interaction (UI): None - No victim interaction required
- Scope (S): Unchanged - Impact limited to vulnerable component
- Confidentiality (C): None - No confidentiality impact
- Integrity (I): Low - Limited integrity impact
- Availability (A): None - No availability impact
The EPSS (Exploit Prediction Scoring System) probability is 0.032% with a percentile of 8.721, indicating a relatively low likelihood of exploitation in the wild.
Root Cause
The root cause of CVE-2025-13129 lies in the application's failure to properly validate and enforce the expected sequence of operations within its behavioral workflow. The Onaylarım software does not adequately verify that users are following the prescribed workflow paths, allowing authenticated users to skip steps or perform actions out of sequence.
This type of vulnerability typically occurs when applications rely solely on client-side workflow enforcement or fail to implement proper server-side state validation between workflow steps.
Attack Vector
The attack vector is network-based, requiring the attacker to have low-level privileges (authenticated access) to the Onaylarım application. The attacker can exploit the vulnerability by:
- Authenticating to the Onaylarım application with valid credentials
- Identifying workflow steps that can be bypassed or manipulated
- Directly accessing functionality that should require prior workflow steps
- Submitting requests that skip mandatory approval or verification processes
The vulnerability allows functionality misuse through workflow bypass, enabling attackers to circumvent intended business logic controls. For detailed technical information, refer to the Turkish National Cyber Incident Response Center (USOM) advisory.
Detection Methods for CVE-2025-13129
Indicators of Compromise
- Unusual workflow state transitions in application logs
- Users completing processes without expected intermediate steps being logged
- Requests to workflow endpoints that bypass expected sequencing
- Anomalous API calls that skip prerequisite workflow stages
Detection Strategies
Organizations can detect potential exploitation of CVE-2025-13129 through the following methods:
Application Log Analysis: Monitor application logs for workflow state anomalies. Look for sequences where users complete actions without corresponding prerequisite events being recorded.
API Request Monitoring: Track API requests to identify direct calls to workflow endpoints that should only be accessible after completing prior steps.
Behavioral Analytics: Implement user behavioral analytics to detect patterns inconsistent with normal workflow progression through the Onaylarım application.
Session State Auditing: Review session state data to identify instances where workflow state appears manipulated or inconsistent with expected progression.
Monitoring Recommendations
Security teams should implement comprehensive monitoring for workflow integrity:
- Enable detailed logging for all workflow-related operations in the Onaylarım application
- Configure alerts for unexpected workflow state transitions
- Monitor for users accessing restricted workflow stages without proper prerequisites
- Implement network-level monitoring for suspicious request patterns to application endpoints
- Review audit logs regularly for signs of workflow manipulation
How to Mitigate CVE-2025-13129
Immediate Actions Required
- Review and audit all Onaylarım deployments within the organization
- Implement enhanced logging for workflow operations
- Restrict network access to the Onaylarım application to authorized users only
- Monitor for suspicious workflow activity patterns
- Consult the USOM advisory for vendor-specific guidance
Patch Information
Organizations running affected versions of Onaylarım (versions 25.09.26.01 through 18112025) should consult with Seneka Software Hardware Information Technology Trade Contracting and Industry Ltd. Co. for patch availability and upgrade instructions.
Refer to the official advisory from the Turkish National Cyber Incident Response Center (USOM) at https://www.usom.gov.tr/bildirim/tr-25-0422 for the latest remediation guidance and vendor updates.
Workarounds
If immediate patching is not possible, organizations should consider the following interim mitigations:
- Network Segmentation: Isolate the Onaylarım application behind additional network controls to limit exposure
- Enhanced Authentication: Implement additional authentication requirements for sensitive workflow operations
- Access Control Review: Audit and restrict user privileges to minimum necessary permissions
- Manual Workflow Verification: Implement manual review processes for critical workflow completions until patches are applied
- Web Application Firewall: Configure WAF rules to detect and block suspicious request patterns targeting workflow endpoints
