CVE-2020-15418 Vulnerability Summary

CVE-2020-15418: This vulnerability allows remote attackers to disclose sensitive information on affected installations of Veeam ONE 10.0.0.750_20200415. Authentication is not required to exploit this vulnerability. The specific flaw exists within the SSRSReport class. Due to the improper restriction of XML External Entity (XXE) references, a specially crafted document specifying a URI causes the XML parser to access the URI and embed the contents back into the XML document for further processing. An attacker can leverage this vulnerability to disclose file contents in the context of SYSTEM. Was ZDI-CAN-10709.

Assessing the Risk of CVE-2020-15418

Access Complexity Graph

The exploitability of CVE-2020-15418 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-2020-15418

With low attack complexity and no required privileges, CVE-2020-15418 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-2020-15418, 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-2020-15418, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.

  • Confidentiality: High
    Exploiting CVE-2020-15418 can result in unauthorized access to sensitive data, severely compromising data privacy.
  • Integrity: None
    CVE-2020-15418 poses no threat to data integrity.
  • Availability: None
    CVE-2020-15418 does not impact system availability.

CWE Common Weakness Enumeration

CWE-611

CAPEC Common Attack Pattern Enumeration and Classification

  • Data Serialization External Entities Blowup CAPEC-221 This attack takes advantage of the entity replacement property of certain data serialization languages (e.g., XML, YAML, etc.) where the value of the replacement is a URI. A well-crafted file could have the entity refer to a URI that consumes a large amount of resources to create a denial of service condition. This can cause the system to either freeze, crash, or execute arbitrary code depending on the URI.
