Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Tiki Wiki CMS suffers from **OS Command Injection**. π **Consequences**: Attackers can execute arbitrary system commands, leading to total server compromise, data theft, or service disruption.β¦
π‘οΈ **Root Cause**: **CWE-78** (Improper Neutralization of Special Elements used in an OS Command). The software fails to sanitize user input before passing it to the OS, allowing malicious payloads to slip through.
Q3Who is affected? (Versions/Components)
π₯ **Affected**: **Tiki Wiki CMS**. Specifically, all versions **prior to version 28**. If you are running v27 or lower, you are vulnerable. π¦ Vendor: Tiki Wiki.
Q4What can hackers do? (Privileges/Data)
π **Attacker Capabilities**: With **CVSS 3.1 (Critical)**, attackers gain **High** Confidentiality, Integrity, and Availability impact.β¦
π **Exploitation Threshold**: **LOW**. The CVSS vector shows **AV:N** (Network), **AC:L** (Low Complexity), **PR:N** (No Privileges Required), and **UI:N** (No User Interaction).β¦
π **Public Exploit**: The provided data lists **no public PoCs or exploits** (POCs: []). However, given the low complexity and network accessibility, wild exploitation is highly likely to emerge quickly. Stay alert! β οΈ
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for **Tiki Wiki CMS** instances. Check the version number in the footer or admin panel. If it is **< 28**, you are at risk.β¦
