CVE-2018-2380

What is SAP CRM?

SAP Customer Relationship Management (CRM) is a core module of SAP's enterprise software suite, used by large organizations to manage sales, marketing, and customer service processes across the business. SAP CRM environments typically hold sensitive customer data and are deeply integrated with other SAP business systems (ERP, finance), making them a high-value target — a foothold in SAP CRM can be a stepping stone toward broader access across an organization's SAP landscape.

Overview

CVE-2018-2380 is a path traversal vulnerability in SAP CRM that stems from insufficient validation of path information supplied by users. An attacker who already holds high privileges within the application can exploit the flaw to access files or resources outside the directory the application intended to restrict them to, resulting in limited but real confidentiality, integrity, and availability impact.

Technical Details

The vulnerability is classified under CWE-22 (path traversal): user-supplied path segments are used to construct a file system path without properly normalizing or restricting directory-escape sequences (such as ../), allowing access to files the application logic did not intend to expose. The CVSS vector reflects that meaningful privileges are required to reach the vulnerable functionality (PR:H), and that the resulting impact — while real — is limited (low across confidentiality, integrity, and availability) rather than a full system compromise on its own.

Discovery

SAP addressed this vulnerability through its regular monthly Security Patch Day process (March 2018), which is how the vast majority of SAP vulnerabilities are disclosed and fixed. No specific third-party researcher credit is confidently documented for this individual CVE.

Exploitation Context

CISA's KEV catalog confirms this vulnerability has been exploited in the wild, and its ransomwareUse: true marker indicates it has been observed or associated with ransomware operations — consistent with a broader trend of ransomware actors and other threat groups increasingly targeting unpatched SAP environments, which often run business-critical processes and are attractive, high-impact targets once initial access (often via a separately compromised privileged account) is obtained.

Remediation

1. Apply the SAP Security Note associated with CVE-2018-2380 (SAP's March 2018 Security Patch Day) to all affected SAP CRM systems.
2. Review and tighten privilege assignments within SAP CRM, since exploitation requires an attacker to already hold elevated privileges — limiting who holds those roles reduces exposure.
3. Monitor SAP system logs for anomalous file access patterns or path traversal attempts targeting CRM components.
4. Ensure SAP systems are not directly exposed to the internet and are protected behind appropriate network segmentation and access controls.
5. Establish a regular cadence for applying SAP Security Notes, given how frequently SAP vulnerabilities of this class are disclosed and subsequently targeted.
