CVE-2022-22110

7.5 HIGH

📋 TL;DR

Daybyday CRM versions 1.1 through 2.2.0 allow users to set extremely weak passwords (including single-character passwords) when updating their credentials. This vulnerability enables attackers to brute-force user accounts with minimal computational effort. Organizations using affected versions of Daybyday CRM are at risk.

💻 Affected Systems

Products:
  • Daybyday CRM
Versions: 1.1 through 2.2.0
Operating Systems: All
Default Config Vulnerable: ⚠️ Yes
Notes: All installations with default password update functionality are vulnerable.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers gain unauthorized access to all user accounts through trivial brute-force attacks, leading to complete system compromise, data theft, and privilege escalation.

🟠

Likely Case

Attackers compromise individual user accounts through automated password guessing, potentially accessing sensitive CRM data and performing unauthorized actions.

🟢

If Mitigated

With strong password policies and monitoring, impact is limited to failed login attempts that trigger alerts.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: LIKELY
Unauthenticated Exploit: ✅ No
Complexity: LOW

Exploitation requires user credentials to access password update functionality, but weak passwords can then be brute-forced trivially.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 2.2.1 and later

Vendor Advisory: https://github.com/Bottelet/DaybydayCRM/commit/a0392f4a4a14e1e3fedaf6817aefce69b6bd661b

Restart Required: No

Instructions:

1. Update Daybyday CRM to version 2.2.1 or later. 2. Apply the patch from the GitHub commit. 3. No restart required.

🔧 Temporary Workarounds

Enforce Strong Password Policy

all

Implement server-side password validation requiring minimum length (8+ characters), complexity, and prevent common weak passwords.

Modify password validation logic in user update functionality

🧯 If You Can't Patch

  • Enforce strong password policies through external authentication systems (e.g., LDAP/AD integration).
  • Implement account lockout policies after failed login attempts and monitor authentication logs.

🔍 How to Verify

Check if Vulnerable:

Attempt to update a user password to a single character via the user update functionality. If successful, the system is vulnerable.

Check Version:

Check Daybyday CRM version in admin panel or configuration files.

Verify Fix Applied:

After patching, attempt to set a weak password (single character). The system should reject it with appropriate error messages.

📡 Detection & Monitoring

Log Indicators:

  • Multiple failed login attempts from single IP
  • Successful login after many failures
  • Password update requests with weak passwords

Network Indicators:

  • Unusual authentication traffic patterns
  • Brute-force attack tools traffic

SIEM Query:

source="daybyday_logs" AND (event="failed_login" OR event="password_change") | stats count by src_ip, user
