CVE-2024-58258: SugarCRM API Module SSRF Vulnerability

CVE-2024-58258 Overview

CVE-2024-58258 is a Server-Side Request Forgery (SSRF) vulnerability affecting SugarCRM versions before 13.0.4 and 14.x before 14.0.1. The flaw resides in the API module, where a limited form of code injection enables attackers to coerce the server into issuing arbitrary outbound requests. The issue is classified under [CWE-94] (Improper Control of Generation of Code).

The vulnerability is exploitable over the network without authentication or user interaction. It carries an EPSS probability of 13.248% at the 95.87 percentile, indicating elevated likelihood of exploitation relative to the broader CVE population. A public proof-of-concept is referenced through Exploit-DB and the Full Disclosure mailing list.

Critical Impact
Unauthenticated attackers can abuse the SugarCRM API module to perform SSRF, pivot into internal networks, and access internal services that trust the SugarCRM host.

Affected Products

SugarCRM versions prior to 13.0.4
SugarCRM 14.x versions prior to 14.0.1
SugarCRM API module (all deployments running affected versions)

Technical Details for CVE-2024-58258

Vulnerability Analysis

The vulnerability exists in the SugarCRM API module, where input handling permits a limited form of code injection. This injection primitive does not yield full remote code execution but provides enough control to influence outbound HTTP request construction. The result is a Server-Side Request Forgery condition where the SugarCRM server makes attacker-directed requests on behalf of the adversary.

Because the API module is exposed over the network and the attack requires no privileges or user interaction, an attacker can reach the vulnerable code path from any system that can communicate with the SugarCRM web interface. The scope change reflected in the advisory indicates that exploitation impacts resources beyond the vulnerable component itself, such as internal services reachable from the application server.

Root Cause

The root cause is improper neutralization of input passed into a code-evaluation path within the API module. Untrusted data influences code generation or interpretation, which then affects URL or request parameters used by server-side HTTP client logic. The dynamic evaluation surface lacks adequate validation and allowlisting of destinations, so the server proxies attacker-supplied requests without restriction.

Attack Vector

An unauthenticated remote attacker sends a crafted request to the SugarCRM API endpoint. The injected fragment alters the server's request construction, causing the application to issue HTTP requests to arbitrary internal or external hosts. Attackers commonly target cloud metadata services such as 169.254.169.254, internal admin panels, or non-routable RFC1918 ranges to enumerate and access services that trust the SugarCRM host's network position.

Technical details are referenced in the SugarCRM Security Advisory SA-2024-059 and the Full Disclosure Security Post.

Detection Methods for CVE-2024-58258

Indicators of Compromise

Outbound HTTP requests from the SugarCRM application server to internal IP ranges (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16) or to cloud metadata endpoints such as 169.254.169.254.
Anomalous API requests containing encoded payloads, expression-like syntax, or URL parameters targeting the SugarCRM API module.
Web server logs showing repeated POST or GET requests to /rest/v10/ endpoints from a single source with varied payload structures.

Detection Strategies

Inspect web access logs for API requests containing suspicious characters used in code-injection primitives, such as backticks, ${}, or serialized object markers.
Correlate inbound API traffic with outbound HTTP connections initiated by the SugarCRM process to identify SSRF pivots.
Compare SugarCRM application version against the patched releases (13.0.4, 14.0.1) using configuration management or vulnerability scanners.

Monitoring Recommendations

Alert on any egress traffic from the SugarCRM server destined for cloud metadata services or internal management interfaces.
Monitor for new or unexpected DNS resolutions originating from the SugarCRM application process.
Enable verbose API request logging and forward to a SIEM for retroactive hunting on the injection patterns described in advisory SA-2024-059.

How to Mitigate CVE-2024-58258

Immediate Actions Required

Upgrade SugarCRM to version 13.0.4 or 14.0.1 or later as the primary remediation.
Restrict egress traffic from the SugarCRM application server using host-based or network firewalls, denying access to internal management ranges and cloud metadata endpoints.
Place the SugarCRM API behind an authenticated reverse proxy or web application firewall while patching is scheduled.
Audit recent API logs and outbound connections for evidence of prior exploitation attempts.

Patch Information

SugarCRM has released fixed builds in versions 13.0.4 and 14.0.1. Refer to SugarCRM Security Advisory SA-2024-059 for vendor guidance, upgrade procedures, and release notes. Cloud-hosted SugarCRM instances managed by the vendor receive patches directly; on-premises deployments must apply the update manually.

Workarounds

Enforce strict egress filtering so the SugarCRM server can only reach known-required external services.
Block access to the API module from untrusted networks at the perimeter until the upgrade is complete.
Require authentication and IP allowlisting on reverse proxies fronting the SugarCRM deployment.
Disable or isolate cloud instance metadata service access using IMDSv2 enforcement or hop-limit restrictions where applicable.
