HPE NonStop Web ViewPoint Enterprise software: Exposure of Sensitive Information to an Unauthorized Actor
CVE-2024-22435 is a high-severity exposure of sensitive information to an unauthorized actor vulnerability in HPE NonStop Web ViewPoint Enterprise software from Hewlett Packard Enterprise, with a CVSS 3.1 base score of 8.3 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. The record lists versions T0986L01^AAZ, T0986H01^AAY as the first without the flaw, so updating HPE NonStop Web ViewPoint Enterprise software to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.44% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update HPE NonStop Web ViewPoint Enterprise software to T0986L01^AAZ or T0986H01^AAY, whichever matches your release line, or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description
A potential security vulnerability has been identified in Web ViewPoint Enterprise software. This vulnerability could be exploited to allow unauthorized users to access some resources on a NonStop system.

The underlying weakness: Exposure of Sensitive Information to an Unauthorized Actor
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
How developers prevent this class of flaw
- Compartmentalize the system to have safe areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
