This CVE describes an open redirect vulnerability in Loway software where attackers can redirect users to malicious websites. It affects systems running vulnerable versions of Loway products, potentially allowing phishing attacks or credential theft.
💻 Affected Systems
- Loway software products
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Users could be redirected to malicious sites that steal credentials, install malware, or conduct phishing attacks, potentially leading to account compromise or system infection.
Likely Case
Attackers redirect users to phishing sites to steal login credentials or personal information, which could lead to account takeover or data theft.
If Mitigated
With proper input validation and URL filtering, redirects would only go to trusted domains, preventing exploitation.
🎯 Exploit Status
Open redirect vulnerabilities typically require minimal technical skill to exploit once the vulnerable endpoint is identified.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified
Vendor Advisory: https://www.gov.il/en/Departments/faq/cve_advisories
Restart Required: No
Instructions:
1. Monitor Loway vendor announcements for patches. 2. Apply patches when available. 3. Test in non-production environment first.
🔧 Temporary Workarounds
Input Validation Filter
allImplement server-side validation to only allow redirects to trusted domains
Implement URL validation in application code to check redirect destinations against allowlist
Web Application Firewall Rule
allBlock redirects to external/untrusted domains
Configure WAF to detect and block redirects containing external domains
🧯 If You Can't Patch
- Implement strict input validation to only allow redirects to pre-approved internal domains
- Deploy web application firewall with rules to detect and block open redirect attempts
🔍 How to Verify
Check if Vulnerable:
Test redirect functionality by attempting to redirect to external domains using URL parametersCheck Version:
Check Loway product documentation for version identification methodsVerify Fix Applied:
Verify that redirects only work for approved internal domains and external redirects are blocked📡 Detection & Monitoring
Log Indicators:
- Unusual redirect patterns in web server logs
- Multiple redirect attempts to external domains
Network Indicators:
- HTTP 302/301 redirects to suspicious external domains
- Unusual outbound traffic patterns following redirects
SIEM Query:
source="web_server" AND (status=302 OR status=301) AND url CONTAINS "redirect=" AND url CONTAINS "http://"
