Exploitability
| CWE ID | Description |
|---|---|
| CWE-74 | The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. |
| CWE-89 | The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data. |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability exists in the Tiobon Employee Self-Service System up to version 7.2, specifically in the /Blog/BlogSearch.aspx file within the Login Endpoint component. It involves the manipulation of the 'Keyword' argument, which leads to a SQL injection vulnerability. This means an attacker can inject malicious SQL code remotely through this parameter.
How can this vulnerability impact me? :
The SQL injection vulnerability allows an attacker to remotely execute arbitrary SQL commands on the affected system. This can lead to unauthorized access to sensitive data, data modification, or disruption of the system's normal operation. Since the exploit is publicly available, the risk of exploitation is increased.
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability involves SQL injection via the Keyword argument in the /Blog/BlogSearch.aspx endpoint of the Tiobon Employee Self-Service System. Detection can be attempted by monitoring for unusual or suspicious HTTP requests targeting this endpoint with SQL injection payloads.
- Use web application firewall (WAF) logs or intrusion detection system (IDS) rules to detect SQL injection patterns in requests to /Blog/BlogSearch.aspx.
- Run network traffic captures and filter HTTP requests to /Blog/BlogSearch.aspx, looking for suspicious parameters in the Keyword argument.
- Example command to capture such traffic using tcpdump (replace interface and host as needed): tcpdump -i eth0 -A 'tcp port 80 and (((ip[2:2] - ((ip[0]&0xf)<<2)) - ((tcp[12]&0xf0)>>2)) != 0)' | grep '/Blog/BlogSearch.aspx'
- Use curl or similar tools to test the endpoint with known SQL injection payloads in the Keyword parameter to verify vulnerability presence.
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include restricting or filtering access to the vulnerable endpoint and sanitizing input parameters to prevent SQL injection.
- Apply input validation and parameterized queries or prepared statements in the application code handling the Keyword argument.
- If possible, block or limit remote access to /Blog/BlogSearch.aspx until a patch or fix is available.
- Deploy a web application firewall (WAF) with rules to detect and block SQL injection attempts targeting this endpoint.
- Monitor logs for suspicious activity and respond promptly to any detected exploitation attempts.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
The vulnerability is a SQL injection in the Tiobon Employee Self-Service System that could allow unauthorized access or manipulation of data through the Login Endpoint. Such vulnerabilities can potentially lead to unauthorized disclosure or alteration of personal or sensitive data.
While the provided information does not explicitly mention compliance impacts, SQL injection vulnerabilities generally pose risks to compliance with standards like GDPR and HIPAA because they can lead to breaches of confidentiality, integrity, and availability of protected data.
Therefore, this vulnerability could negatively affect compliance with regulations that require protection of personal and sensitive information by exposing systems to data breaches.
