Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: A SQL Injection (SQLi) flaw in Nagios XI. <br>๐ฅ **Consequences**: Attackers can execute arbitrary SQL commands via the `key1` parameter.โฆ
๐ก๏ธ **Root Cause**: Improper input validation in the `admin/info.php` script. <br>๐ **Flaw**: The `key1` parameter is not sanitized before being used in SQL queries.โฆ
๐ฆ **Affected**: Nagios XI versions **before 5.4.13**. <br>๐ **Vendor**: Nagios Corporation. <br>โ ๏ธ **Scope**: Any deployment running these older versions is at risk.
Q4What can hackers do? (Privileges/Data)
๐ต๏ธ **Capabilities**: Remote attackers can run **arbitrary SQL commands**. <br>๐ **Impact**: Potential access to sensitive database data, user credentials, or system configuration.โฆ
โก **Threshold**: **Low**. <br>๐ **Auth**: Requires remote access to the web interface. <br>โ๏ธ **Config**: Exploitable via the `key1` parameter in `admin/info.php`. No complex setup needed.
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ **Public Exp**: **Yes**. <br>๐ **PoCs**: Available on GitHub (ProjectDiscovery Nuclei, Chaitin Xray). <br>๐ **Status**: Automated scanning tools can detect and exploit this easily.
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: Scan for Nagios XI versions < 5.4.13. <br>๐งช **Test**: Use Nuclei templates or Xray plugins targeting `admin/info.php?key1=`. <br>๐ **Tools**: Look for SQL error responses or unexpected data leakage.
Q8Is it fixed officially? (Patch/Mitigation)
โ **Fixed**: **Yes**. <br>๐ง **Patch**: Upgrade to **Nagios XI 5.4.13** or later. <br>๐ข **Release**: Advisory published May 16, 2018.
Q9What if no patch? (Workaround)
๐ง **Workaround**: If patching is delayed, restrict network access to `admin/info.php`. <br>๐ **Mitigation**: Implement WAF rules to block SQL injection patterns in the `key1` parameter.โฆ
๐ฅ **Urgency**: **High**. <br>๐ **Priority**: Patch immediately. <br>โณ **Reason**: Public PoCs exist, and SQLi is a critical risk. Do not leave older versions exposed.
