CVE-2024-42374 Vulnerability Summary

CVE-2024-42374: BEx Web Java Runtime Export Web Service does not sufficiently validate an XML document accepted from an untrusted source. An attacker can retrieve information from the SAP ADS system and exhaust the number of XMLForm service which makes the SAP ADS rendering (PDF creation) unavailable. This affects the confidentiality and availability of the application.

Assessing the Risk of CVE-2024-42374

Access Complexity Graph

The exploitability of CVE-2024-42374 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).

Exploitability Analysis for CVE-2024-42374

With low attack complexity and no required privileges, CVE-2024-42374 is an easy target for cybercriminals. Organizations should prioritize immediate mitigation measures to prevent unauthorized access and data breaches.

Understanding AC and PR

A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.

Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.

Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.

CVSS Score Breakdown Chart

Above is the CVSS Sub-score Breakdown for CVE-2024-42374, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.

CIA Impact Analysis

Below is the Impact Analysis for CVE-2024-42374, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.

  • Confidentiality: Low
    CVE-2024-42374 could lead to minor leaks of non-critical information without major privacy breaches.
  • Integrity: None
    CVE-2024-42374 poses no threat to data integrity.
  • Availability: High
    CVE-2024-42374 can disrupt system operations, potentially causing complete denial of service (DoS).

Exploit Prediction Scoring System (EPSS)

The EPSS score estimates the probability that this vulnerability will be exploited in the near future.

EPSS Score: 0.046% (probability of exploit)

EPSS Percentile: 19.86% (lower percentile = lower relative risk)
This vulnerability is less risky than approximately 80.14% of others.

CWE Common Weakness Enumeration

CWE-91

CAPEC Common Attack Pattern Enumeration and Classification

  • XML Injection CAPEC-250 An attacker utilizes crafted XML user-controllable input to probe, attack, and inject data into the XML database, using techniques similar to SQL injection. The user-controllable input can allow for unauthorized viewing of data, bypassing authentication or the front-end application for direct XML database access, and possibly altering database information.
  • XPath Injection CAPEC-83 An attacker can craft special user-controllable input consisting of XPath expressions to inject the XML database and bypass authentication or glean information that they normally would not be able to. XPath Injection enables an attacker to talk directly to the XML database, thus bypassing the application completely. XPath Injection results from the failure of an application to properly sanitize input used as part of dynamic XPath expressions used to query an XML database.
