Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: SQL Injection in `color.php` via the `filter` parameter. <br>๐ฅ **Consequences**: Remote attackers can execute **arbitrary commands** on the server. This is not just data theft; it's full system compromise.
Q2Root Cause? (CWE/Flaw)
๐ก๏ธ **Root Cause**: Improper neutralization of special elements used in an SQL command (**SQL Injection**). The `filter` parameter in `color.php` is not sanitized before being used in database queries.
Q3Who is affected? (Versions/Components)
๐ฆ **Affected**: **Cacti** versions **1.2.12** and likely earlier. <br>๐ง **Component**: Specifically the `color.php` file within the Cacti web application.
Q4What can hackers do? (Privileges/Data)
๐ **Attacker Capabilities**: <br>1. **Remote Code Execution (RCE)**: Execute commands as the web server user. <br>2. **Full Control**: Gain reverse shells (as shown in PoCs). <br>3.โฆ
๐ **Threshold**: **Medium**. <br>โ **Auth Required**: Yes, you need valid Cacti credentials (Username/Password). <br>โ ๏ธ **Config**: Must be accessible via HTTP/HTTPS.
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ฅ **Public Exploits**: **YES**. <br>๐ Multiple PoCs available on GitHub (e.g., `gimme-a-shell.py`, `cacti_sqli_rce.py`).โฆ
๐ **Self-Check**: <br>1. **Scan**: Use Nuclei or Nessus for CVE-2020-14295 signatures. <br>2. **Manual**: Check if `color.php` exists in `/cacti/`. <br>3. **Verify**: Look for version `1.2.12` in the login page footer.
Q8Is it fixed officially? (Patch/Mitigation)
๐ฉน **Official Fix**: **YES**. <br>๐ **Patch Date**: June 2020. <br>๐ข **Advisories**: SUSE, Fedora, and Gentoo have issued security updates. Update Cacti to the latest stable version immediately.
Q9What if no patch? (Workaround)
๐ง **No Patch Workaround**: <br>1. **Restrict Access**: Block access to `color.php` via WAF or Nginx/Apache rules. <br>2. **Network Segmentation**: Isolate Cacti servers from untrusted networks. <br>3.โฆ
โก **Urgency**: **HIGH**. <br>๐จ **Priority**: **P1**. <br>๐ก **Reason**: RCE vulnerability with available PoCs. Even though auth is required, many admins use weak/default credentials.โฆ
