Vulnerability Data

Fides is an open-source privacy engineering platform for managing the fulfillment of data privacy requests in your runtime environment, and the enforcement of privacy regulations in your code. The Fides web application allows data subject users to request access to…

their personal data. If the request is approved by the data controller user operating the Fides web application, the data subject's personal data can then retrieved from connected systems and data stores before being bundled together as a data subject access request package for the data subject to download. Supported data formats for the package include json and csv, but the most commonly used format is a series of HTML files compressed in a ZIP file. Once downloaded and unzipped, the data subject user can browse the HTML files on their local machine. It was identified that there was no validation of input coming from e.g. the connected systems and data stores which is later reflected in the downloaded data. This can result in an HTML injection that can be abused e.g. for phishing attacks or malicious JavaScript code execution, but only in the context of the data subject's browser accessing a HTML page using the `file://` protocol. Exploitation is limited to rogue Admin UI users, malicious connected system / data store users, and the data subject user if tricked via social engineering into submitting malicious data themselves. This vulnerability has been patched in version 2.23.3.

Adversaries with SYSTEM access to a host may attempt to access Local Security Authority (LSA) secrets, which can contain a variety of different credential materials, such as credentials for service accounts.
T1003.005 Cached Domain Credentials Credential Access
Adversaries may attempt to access cached domain credentials used to allow authentication to occur in the event a domain controller is unavailable.
T1007 System Service Discovery Discovery
Adversaries may try to gather information about registered local system services.
T1011 Exfiltration Over Other Network Medium Exfiltration
Adversaries may attempt to exfiltrate data over a different network medium than the command and control channel.
T1012 Query Registry Discovery
Adversaries may interact with the Windows Registry to gather information about the system, configuration, and installed software.

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-79

Penetration testing submits XSS payloads to web applications, detecting cross-site scripting flaws for subsequent remediation.

addresses: CWE-79

Validates web inputs to reject script-related content that could produce XSS.

addresses: CWE-79

Output validation against expected content can reject or sanitize script content in generated web pages, reducing XSS exploitability.

PR.PS-06 mostly match
blocks

Secure SDLC practices directly target introduction of XSS via coding standards/testing (mostly), yet the single broad outcome leaves many specific neutralization vectors unaddressed (partial).

PR.PS-02 partial match
blocks

Patching and EOL replacement can remediate known XSS instances in libraries or frameworks (partial) but do nothing to enforce input neutralization in application code (none).
