2. UPDATE INFORMATION
This updated advisory is a follow-up to the advisory update titled ICSMA-21-87-01 Philips Vue PACS (Update A) that was published January 20, 2022, to the ICS webpage on www.cisa.gov/uscert/ics.
3. RISK EVALUATION
Successful exploitation of these vulnerabilities could allow an unauthorized person or process to eavesdrop, view or modify data, gain system access, perform code execution, install unauthorized software, or affect system data integrity in such a way as to negatively impact the confidentiality, integrity, or availability of the system.
4. TECHNICAL DETAILS
4.1 AFFECTED PRODUCTS
Philips reports these vulnerabilities affect the following Vue PACS products:
- Vue PACS: Versions 12.2.x.x and prior
- Vue MyVue: Versions 12.2.x.x and prior
- Vue Speech: Versions 12.2.x.x and prior
- Vue Motion: Versions 184.108.40.206 and prior
4.2 VULNERABILITY OVERVIEW
The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
The software performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This vulnerability exists within a third party software component (Redis).
When an actor claims to have a given identity, the software does not prove or insufficiently proves that the claim is correct. This vulnerability exists within a third party software component (Redis).
The software initializes or sets a resource with a default that is intended to be changed by the administrator, but the default is not secure.
The product uses a cryptographic key or password past its expiration date, which diminishes its safety significantly by increasing the timing window for cracking attacks against that key.
The software does not initialize or incorrectly initializes a resource, which might leave the resource in an unexpected state when it is accessed or used. This vulnerability exists within a third party software component (7-Zip).
The software does not follow certain coding rules for development, which can lead to resultant weaknesses or increase the severity of the associated vulnerabilities.
The use of a broken or risky cryptographic algorithm is an unnecessary risk that may result in the exposure of sensitive information.
The product does not use or incorrectly uses a protection mechanism that provides sufficient defense against directed attacks against the product.
Weaknesses in this category is related to a software system's data integrity components. This vulnerability exists within a third party software component (Oracle Database).
4.2.11 CROSS-SITE SCRIPTING CWE-79
The software does not neutralize or incorrectly neutralizes user-controllable input before it is placed in an output used as a webpage that is served to other users.
The product does not ensure or incorrectly ensures structured messages or data are well formed and that certain security properties are met before being read from an upstream component or sent to a downstream component.
The software does not properly handle when an input contains Unicode encoding.
The product transmits or stores authentication credentials, but it uses an insecure method susceptible to unauthorized interception and/or retrieval.
The software transmits sensitive or security-critical data in cleartext in a communication channel that can be sniffed by unauthorized actors.
The VideoStream function allows authenticated users access to files stored outside the web root.

CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities. Specifically, users should:
- Minimize network exposure for all control system devices and/or systems, and ensure that they are not accessible from the Internet.
- Locate control system networks and remote devices behind firewalls, and isolate them from the business network.
- When remote access is required, use secure methods, such as Virtual Private Networks (VPNs), recognizing that VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize that VPN is only as secure as the connected devices.
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov. Several recommended practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
Additional mitigation guidance and recommended practices are publicly available on the ICS webpage on cisa.gov in the Technical Information Paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies.
Organizations observing any suspected malicious activity should follow their established internal procedures and report their findings to CISA for tracking and correlation against other incidents.
No known public exploits specifically target these vulnerabilities.
