Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: SQL Injection in Roundcube Webmail via `search` or `search_params`. ๐ฅ **Consequences**: Attackers can manipulate database queries, potentially leading to data exfiltration or system compromise.
Q2Root Cause? (CWE/Flaw)
๐ **Root Cause**: Improper input validation in search parameters. โ ๏ธ **Flaw**: Allows SQL commands to be injected directly into the query logic via specific GET/POST parameters.
Q3Who is affected? (Versions/Components)
๐ฆ **Affected**: Roundcube Webmail. ๐ **Versions**: Before 1.3.17 AND 1.4.x before 1.4.12. ๐ **Status**: All older versions are vulnerable.
Q4What can hackers do? (Privileges/Data)
๐ต๏ธ **Hackers Can**: Execute arbitrary SQL. ๐ค **Data Risk**: Exfiltrate emails, user credentials, and address book data. ๐ด **Privilege**: Potentially gain unauthorized access to backend database contents.
Q5Is exploitation threshold high? (Auth/Config)
๐ **Threshold**: Low to Medium. ๐ **Access**: Requires web access to the Roundcube interface. ๐ **Auth**: Likely requires valid user credentials to trigger the search function, but no complex config needed.
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ฃ **Public Exp?**: YES. ๐ **PoC**: Available on GitHub (pentesttoolscom/roundcube-cve-2021-44026). ๐ **Wild Exploitation**: High risk due to easy-to-use demo scripts.
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: Scan for Roundcube instances. ๐งช **Test**: Use the provided PoC against the `search` parameter. ๐ **Indicator**: Look for SQL error messages or unexpected data in search results.
Q8Is it fixed officially? (Patch/Mitigation)
โ **Fixed?**: YES. ๐ก๏ธ **Patch**: Upgrade to Roundcube 1.3.17+ or 1.4.12+. ๐ข **Advisories**: Debian DSA-5013 and Fedora updates released.
Q9What if no patch? (Workaround)
๐ง **No Patch?**: Restrict web access to Roundcube. ๐ซ **WAF**: Block SQL injection patterns in `search_params`. ๐ **Disable**: Temporarily disable the search feature if possible.
Q10Is it urgent? (Priority Suggestion)
๐ฅ **Urgency**: HIGH. ๐ **Priority**: Immediate patching required. ๐ **Impact**: Critical data breach risk for email systems. โณ **Time**: Act now before widespread exploitation.
