CVE-2024-48176
📋 TL;DR
Lylme Spage v1.9.5 has an authentication bypass vulnerability due to missing login attempt limits and static verification codes. Attackers can brute-force credentials to gain unauthorized access to the system backend. All deployments using this vulnerable version are affected.

- Lylme Spage
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with administrative access, data theft, malware deployment, and lateral movement within the network.
Likely Case
Unauthorized access to administrative functions, configuration changes, data exfiltration, and potential privilege escalation.
If Mitigated
Failed login attempts with no system access, logged brute-force attempts triggering alerts.
🎯 Exploit Status
Simple brute-force attack with readily available tools; no authentication required to attempt exploitation.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available, or implement workarounds.
🔧 Temporary Workarounds
Implement Web Application Firewall (WAF) Rules
allConfigure WAF to limit login attempts and block brute-force patterns
# Example for ModSecurity: SecRule REQUEST_URI "@streq /login" "phase:2,id:1001,t:none,block,msg:'Brute force attack detected',chain"
SecRule &IP:BRUTE_FORCE_COUNTER "@gt 5" "setvar:ip.brute_force_counter=+1,expirevar:ip.brute_force_counter=300"
Network-Level Rate Limiting
linuxUse firewall or load balancer to limit connections to login endpoint
# Example iptables: iptables -A INPUT -p tcp --dport 80 -m state --state NEW -m recent --set --name HTTP --rsource
iptables -A INPUT -p tcp --dport 80 -m state --state NEW -m recent --update --seconds 60 --hitcount 20 --name HTTP --rsource -j DROP
🧯 If You Can't Patch
- Isolate the system behind a VPN or restrict access to trusted IP addresses only
- Implement multi-factor authentication (MFA) at the network or application layer
🔍 How to Verify
Check if Vulnerable:
Test login page: attempt multiple failed logins with same verification code; if system doesn't lock out or refresh code, it's vulnerable.
Check Version:
Check application version in admin panel or configuration files; look for 'v1.9.5' in source code or documentation.
Verify Fix Applied:
After implementing controls, verify that multiple failed login attempts trigger account lockout or rate limiting.
📡 Detection & Monitoring
Log Indicators:
- Multiple failed login attempts from same IP/user
- Successful login after many failures
- Unusual login patterns outside business hours
Network Indicators:
- High volume of POST requests to login endpoint
- Traffic patterns showing credential stuffing
SIEM Query:
source="*access.log*" (method=POST AND uri="/login") | stats count by src_ip | where count > 10
