CVE-2020-10749 Vulnerability Summary

CVE-2020-10749: A vulnerability was found in all versions of containernetworking/plugins before version 0.8.6, that allows malicious containers in Kubernetes clusters to perform man-in-the-middle (MitM) attacks. A malicious container can exploit this flaw by sending rogue IPv6 router advertisements to the host or other containers, to redirect traffic to the malicious container.

Assessing the Risk of CVE-2020-10749

Access Complexity Graph

The exploitability of CVE-2020-10749 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-2020-10749

This vulnerability, CVE-2020-10749, requires a high level of attack complexity and low privileges, making it difficult but not impossible to exploit. Organizations should ensure robust security configurations to mitigate risks.

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-2020-10749, 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-2020-10749, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.

  • Confidentiality: Low
    CVE-2020-10749 could lead to minor leaks of non-critical information without major privacy breaches.
  • Integrity: Low
    Exploiting CVE-2020-10749 may cause minor changes to data without severely impacting its accuracy.
  • Availability: Low
    CVE-2020-10749 may slightly degrade system performance without fully affecting service availability.

Exploit Prediction Scoring System (EPSS)

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

EPSS Score: 0.094% (probability of exploit)

EPSS Percentile: 42.14% (lower percentile = lower relative risk)
This vulnerability is less risky than approximately 57.86% of others.

CWE Common Weakness Enumeration

CWE-300

CAPEC Common Attack Pattern Enumeration and Classification

  • Leveraging Active Adversary in the Middle Attacks to Bypass Same Origin Policy CAPEC-466 An attacker leverages an adversary in the middle attack (CAPEC-94) in order to bypass the same origin policy protection in the victim's browser. This active adversary in the middle attack could be launched, for instance, when the victim is connected to a public WIFI hot spot. An attacker is able to intercept requests and responses between the victim's browser and some non-sensitive website that does not use TLS.
  • Utilizing REST's Trust in the System Resource to Obtain Sensitive Data CAPEC-57 This attack utilizes a REST(REpresentational State Transfer)-style applications' trust in the system resources and environment to obtain sensitive data once SSL is terminated.
  • DNS Blocking CAPEC-589 An adversary intercepts traffic and intentionally drops DNS requests based on content in the request. In this way, the adversary can deny the availability of specific services or content to the user even if the IP address is changed.
  • IP Address Blocking CAPEC-590 An adversary performing this type of attack drops packets destined for a target IP address. The aim is to prevent access to the service hosted at the target IP address.
  • WiFi MAC Address Tracking CAPEC-612 In this attack scenario, the attacker passively listens for WiFi messages and logs the associated Media Access Control (MAC) addresses. These addresses are intended to be unique to each wireless device (although they can be configured and changed by software). Once the attacker is able to associate a MAC address with a particular user or set of users (for example, when attending a public event), the attacker can then scan for that MAC address to track that user in the future.
  • WiFi SSID Tracking CAPEC-613 In this attack scenario, the attacker passively listens for WiFi management frame messages containing the Service Set Identifier (SSID) for the WiFi network. These messages are frequently transmitted by WiFi access points (e.g., the retransmission device) as well as by clients that are accessing the network (e.g., the handset/mobile device). Once the attacker is able to associate an SSID with a particular user or set of users (for example, when attending a public event), the attacker can then scan for this SSID to track that user in the future.
  • Evil Twin Wi-Fi Attack CAPEC-615 Adversaries install Wi-Fi equipment that acts as a legitimate Wi-Fi network access point. When a device connects to this access point, Wi-Fi data traffic is intercepted, captured, and analyzed. This also allows the adversary to use "adversary-in-the-middle" (CAPEC-94) for all communications.
  • Adversary in the Browser (AiTB) CAPEC-662 An adversary exploits security vulnerabilities or inherent functionalities of a web browser, in order to manipulate traffic between two endpoints.
  • Adversary in the Middle (AiTM) CAPEC-94 An adversary targets the communication between two components (typically client and server), in order to alter or obtain data from transactions. A general approach entails the adversary placing themself within the communication channel between the two components.
