Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: GFI Kerio Control suffers from **HTTP Response Splitting**. π **Consequences**: Attackers can inject malicious headers into 302 redirects.β¦
π **Root Cause**: **CWE-113** (Improper Neutralization of CRLF Sequences in HTTP Headers). π **Flaw**: The `Dest` parameter on certain pages is **not sanitized** before being used in HTTP response headers.β¦
π’ **Vendor**: GFI (Malta). π¦ **Product**: Kerio Control (UTM Solution). π **Affected**: Versions **9.2.5** and likely earlier. π Includes features like Virus Protection & Web Filtering.
Q4What can hackers do? (Privileges/Data)
π **Attacker Actions**: Inject arbitrary HTTP headers. π― **Impact**: High (CVSS H). Can execute **Cross-Site Scripting (XSS)**. Can **Poison Caches**. Can redirect users to malicious sites.β¦
βοΈ **Threshold**: **Low** for Network (AV:N), **Low** for Complexity (AC:L). π« **Auth**: None required (PR:N). π€ **UI**: User Interaction Required (UI:R). π **Verdict**: Easy to exploit if a user clicks a crafted link.
π **Self-Check**: Scan for **HTTP Response Splitting** patterns. π οΈ **Tool**: Use Nuclei with the specific CVE-2024-52875 template. π‘ **Indicator**: Look for abnormal `Dest` parameters in 302 responses.β¦
π§ **No Patch?**: Implement **WAF Rules** to block CRLF characters in `Dest` parameters. π‘οΈ **Input Validation**: Sanitize all user inputs before header generation.β¦
