Technical Details for CVE-2025-0282

Vulnerability Analysis

CVE-2025-0282 is a critical stack-based buffer overflow that allows execution of arbitrary code. The vulnerability is found in network-accessible services of the affected software and can be triggered without authentication.

Root Cause

The vulnerability stems from improper handling of input sizes in network requests, leading to buffer overflows.

Attack Vector

Remote attackers can exploit this vulnerability over a network without needing valid credentials, leveraging crafted network messages.

#include <string.h>
#include <stdio.h>

void vulnerable_function(char *input) {
    char buffer[256];
    strcpy(buffer, input);
}

int main(int argc, char **argv) {
    vulnerable_function(argv[1]);
    printf("Vulnerable function executed!\n");
    return 0;
}

Detection Methods for CVE-2025-0282

Indicators of Compromise

Unusual outbound traffic patterns
Unexpected services running
Modifications to critical files

Detection Strategies

Network monitoring tools should track communications anomalies. Systems should be scanned with updated IDS/IPS signatures that detect attempts to exploit buffer overflows.

Monitoring Recommendations

Implement continuous monitoring with SIEM solutions that focus on unusual application behavior and alert on excessive memory usage.

How to Mitigate CVE-2025-0282

Immediate Actions Required

Disable vulnerable services if not necessary
Use firewall rules to block untrusted IP addresses
Monitor systems for related IoCs

Patch Information

Ivanti has released patches for affected versions. Users are strongly advised to update to the latest version as per Ivanti's advisory.

Workarounds

In cases where immediate patching is not available, ensure only trusted network zones can communicate with the affected systems. Consider employing additional network segmentation.

bash

# Example mitigation configuration
iptables -A INPUT -p tcp --dport <service-port> -s <trusted-ip-range> -j ACCEPT
iptables -A INPUT -p tcp --dport <service-port> -j DROP
