CVE-2019-9147 Vulnerability Summary

CVE-2019-9147: Mailvelope prior to 3.1.0 is vulnerable to a clickjacking attack against the settings page. As the settings page is intended to be accessible from web applications, the browser's extension isolation mechanisms are disabled (web_accessible_resources). Mailvelope implements additional measures to prevent web applications from directly embedding the settings page, but this mechanism can be bypassed.

Assessing the Risk of CVE-2019-9147

Access Complexity Graph

The exploitability of CVE-2019-9147 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-2019-9147

With low attack complexity and no required privileges, CVE-2019-9147 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-2019-9147, 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-2019-9147, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.

  • Confidentiality: None
    CVE-2019-9147 has no significant impact on data confidentiality.
  • Integrity: Low
    Exploiting CVE-2019-9147 may cause minor changes to data without severely impacting its accuracy.
  • Availability: None
    CVE-2019-9147 does not impact system availability.

Exploit Prediction Scoring System (EPSS)

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

EPSS Score: 0.184% (probability of exploit)

EPSS Percentile: 56.72% (lower percentile = lower relative risk)
This vulnerability is less risky than approximately 43.28% of others.

CWE Common Weakness Enumeration

CWE-1021

CAPEC Common Attack Pattern Enumeration and Classification

  • Clickjacking CAPEC-103 An adversary tricks a victim into unknowingly initiating some action in one system while interacting with the UI from a seemingly completely different, usually an adversary controlled or intended, system.
  • Flash File Overlay CAPEC-181 An attacker creates a transparent overlay using flash in order to intercept user actions for the purpose of performing a clickjacking attack. In this technique, the Flash file provides a transparent overlay over HTML content. Because the Flash application is on top of the content, user actions, such as clicks, are caught by the Flash application rather than the underlying HTML. The action is then interpreted by the overlay to perform the actions the attacker wishes.
  • iFrame Overlay CAPEC-222 In an iFrame overlay attack the victim is tricked into unknowingly initiating some action in one system while interacting with the UI from seemingly completely different system.
  • Task Impersonation CAPEC-504 An adversary, through a previously installed malicious application, impersonates an expected or routine task in an attempt to steal sensitive information or leverage a user's privileges.
  • Tapjacking CAPEC-506 An adversary, through a previously installed malicious application, displays an interface that misleads the user and convinces them to tap on an attacker desired location on the screen. This is often accomplished by overlaying one screen on top of another while giving the appearance of a single interface. There are two main techniques used to accomplish this. The first is to leverage transparent properties that allow taps on the screen to pass through the visible application to an application running in the background. The second is to strategically place a small object (e.g., a button or text field) on top of the visible screen and make it appear to be a part of the underlying application. In both cases, the user is convinced to tap on the screen but does not realize the application that they are interacting with.
  • Cross Frame Scripting (XFS) CAPEC-587 This attack pattern combines malicious Javascript and a legitimate webpage loaded into a concealed iframe. The malicious Javascript is then able to interact with a legitimate webpage in a manner that is unknown to the user. This attack usually leverages some element of social engineering in that an attacker must convinces a user to visit a web page that the attacker controls.
  • Credential Prompt Impersonation CAPEC-654 An adversary, through a previously installed malicious application, impersonates a credential prompt in an attempt to steal a user's credentials.
