Full Report
An improper neutralization of input data has been detected in Times Software E-Payroll, resulting in the possibility of a DoS attack and (potentially) SQL Injection (CVE-2025-9977).
Analysis Summary
# Vulnerability: Improper Input Neutralization in Times Software E-Payroll Leading to DoS/SQLi
## CVE Details
- CVE ID: CVE-2025-9977
- CVSS Score: Information Not Provided (Severity Assessed based on description: High potential given SQLi possibility)
- CWE: CWE-89 (Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection'))
## Affected Systems
- Products: Times Software E-Payroll
- Versions: All through 20250121.0 (and potentially above)
- Configurations: Specifically related to the login process using POST parameters.
## Vulnerability Description
The vulnerability stems from the improper neutralization of input data within one of the POST parameters sent during the login process for Times Software E-Payroll. This flaw allows an unauthenticated attacker to inject malicious data, leading to:
1. Denial of Service (DoS) attacks.
2. Potential SQL Injection (SQLi) attacks (though backend filtering may currently hinder full exploitation).
3. Disclosure of internal infrastructure information via extensive error messages triggered by command injection attempts.
## Exploitation
- Status: PoC available (Implied feasibility via command injection causing errors, although full SQLi exploit proof-of-concept is not explicitly confirmed)
- Complexity: Low (Unauthenticated, network-based attack against login mechanism)
- Attack Vector: Network
## Impact
- Confidentiality: Medium (Information leakage via error messages possible)
- Integrity: High (Potential for SQL Injection)
- Availability: High (Confirmed possibility of DoS attacks)
## Remediation
### Patches
- Vendor response and patching status are currently **unknown** as the vendor (Times Software) has not replied to coordination messages.
### Workarounds
- Since the vulnerability is tied to unauthenticated POST parameters during login, immediate mitigation steps, if known, would be highly dependent on specific application configurations.
- Deploying external Web Application Firewalls (WAFs) to aggressively filter potentially malicious input (SQL metacharacters) in POST requests directed at the login endpoint may offer temporary protection against both DoS and potential SQLi/Command Injection.
## Detection
- **Indicators of Compromise (IOCs):** High volume of specially crafted POST requests targeting the E-Payroll login endpoint, requests containing typical SQL syntax or command injection payloads, and frequent application errors/timeouts indicating resource exhaustion (DoS).
- **Detection Methods and Tools:** Monitor network traffic logs for anomalies in POST data related to the E-Payroll login page. Utilize security tooling capable of deep packet inspection or WAF logs to identify attempts matching CWE-89 patterns.
