CVE-2024-12345: INW Krbyyyzo DoS Vulnerability

CVE-2024-12345 Overview

A resource consumption vulnerability has been identified in INW Krbyyyzo version 25.2002. This vulnerability affects an unknown functionality within the /gbo.aspx file of the Daily Huddle Site component. Through manipulation of the s argument, an attacker can trigger excessive resource consumption, potentially leading to denial of service conditions. The attack requires local access to the host system.

Critical Impact

Local attackers with high privileges can exploit this vulnerability to cause high availability impact through resource exhaustion, potentially disrupting system operations.

Affected Products

• INW Krbyyyzo 25.2002
• Daily Huddle Site component (/gbo.aspx endpoint)
• Additional endpoints may also be affected

Technical Details for CVE-2024-12345

Vulnerability Analysis

This vulnerability falls under CWE-400 (Uncontrolled Resource Consumption), commonly known as a resource exhaustion vulnerability. The flaw exists in the /gbo.aspx file within the Daily Huddle Site component of INW Krbyyyzo. When the s parameter is manipulated with crafted input, the application fails to properly limit resource allocation, leading to excessive consumption of system resources.

The attack requires local access and high privileges, which limits the attack surface but still poses a significant risk in multi-user environments or compromised systems. The vulnerability primarily impacts system availability without affecting confidentiality or integrity.

Root Cause

The root cause of this vulnerability is improper resource management in the /gbo.aspx endpoint. The application does not implement adequate controls to limit the resources consumed when processing the s argument. This allows an authenticated local user with elevated privileges to submit requests that consume disproportionate amounts of system resources such as memory or CPU cycles.

Attack Vector

The attack vector is local, requiring the attacker to have direct access to the host system running the vulnerable INW Krbyyyzo application. The attacker must possess high-level privileges to exploit this vulnerability. By sending specially crafted requests to the /gbo.aspx endpoint with manipulated s parameter values, the attacker can trigger resource exhaustion conditions.

The vulnerability manifests in the Daily Huddle Site component's request handling mechanism. When the s argument receives certain malformed or excessively large input values, the application allocates resources without proper bounds checking. For detailed technical analysis, refer to the VulDB Advisory #293509.

Detection Methods for CVE-2024-12345

Indicators of Compromise

• Unusual resource consumption patterns on systems running INW Krbyyyzo 25.2002
• Repeated requests to /gbo.aspx with abnormal s parameter values
• System performance degradation correlated with Daily Huddle Site activity
• High memory or CPU utilization by the application process

Detection Strategies

• Monitor web server logs for suspicious patterns in requests to /gbo.aspx
• Implement application-level logging to track s parameter values and request frequency
• Configure resource usage thresholds and alerts for the INW Krbyyyzo application
• Deploy endpoint detection solutions to identify abnormal process behavior

Monitoring Recommendations

• Enable verbose logging for the Daily Huddle Site component
• Set up automated alerts for resource utilization anomalies
• Implement request rate limiting on the /gbo.aspx endpoint
• Regularly review access logs for privileged user activity

How to Mitigate CVE-2024-12345

Immediate Actions Required

• Review and restrict access to systems running INW Krbyyyzo 25.2002
• Implement input validation on the s parameter at the application or web server level
• Apply the principle of least privilege to limit users with high-level access
• Monitor systems for signs of active exploitation

Patch Information

No official patch information is currently available from the vendor. Organizations should monitor vendor communications and security advisories for updates. Additional technical details can be found at the VulDB Advisory #293509.

Workarounds

• Implement web application firewall rules to filter malicious requests to /gbo.aspx
• Apply rate limiting to prevent rapid successive requests to the vulnerable endpoint
• Restrict local access to trusted users only until a patch is available
• Consider disabling the Daily Huddle Site component if not business-critical

# Example: Configure resource limits (consult vendor documentation for specific guidance)
# Limit application memory usage
ulimit -v 1048576

# Monitor process resource consumption
top -p $(pgrep -f "krbyyyzo")
