Horizon Alert
Summary of the vulnerability and why it matters
This advisory addresses a vulnerability in pH7 Social Dating CMS that allows attackers to bypass security measures designed to prevent brute-force login attempts. The issue stems from how the system identifies user IP addresses, enabling attackers to circumvent these protections by manipulating specific request headers. While the direct impact on user data is limited, the ability to bypass login security could potentially lead to unauthorized access and disruption of administrative functions. The primary concern is confirming whether this specific technology is in use and, if so, assessing the level of exposure.
- Attackers can bypass login security.
- Protects against repeated unauthorized login attempts.
- Confirm use and assess exposure for this platform.
Attack Path
How an attacker could exploit the issue
An unauthenticated attacker can bypass login attempt throttling by sending specially crafted HTTP headers. This bypass targets the IP address validation mechanism, which is used to limit failed login attempts. By manipulating these headers, an attacker can repeatedly try to log in without being blocked, potentially leading to unauthorized access.
- Network access required.
- Manipulate HTTP headers to trigger.
- Bypass IP-based login throttling.
Live Threat
Current exploitation, exposure, and threat context
This vulnerability could allow an unauthenticated remote attacker to bypass the IP-based throttling mechanism for administrator login attempts. This bypass could be used to repeatedly attempt to log in as an administrator without being blocked due to excessive failed attempts, potentially aiding in brute-force attacks.
- Administrator login attempts.
- Attackers spoof IP headers.
- Facilitates brute-force administrator access.
Operational Fix
Recommended remediation, mitigation, and detection steps
The real-world impact of this vulnerability primarily affects application owners responsible for the pH7 Social Dating CMS. Infrastructure and network/security teams will likely be involved in verifying external reachability and access controls. The initial step is to locate all instances of the affected software, confirm if they are publicly accessible or critical to business operations, and identify the designated owner to assess and plan remediation efforts.
- Application owners should manage this issue.
- Verify public reachability and business criticality.
- Plan remediation based on identified risks.
