Detailsinfo

A vulnerability was found in Siemens Desigo PX Web Module (the affected version unknown). It has been classified as critical. Affected is an unknown part of the component HTTPS Certificate Generation. The manipulation with an unknown input leads to a entropy vulnerability. CWE is classifying the issue as CWE-332. The lack of entropy available for, or used by, a Pseudo-Random Number Generator (PRNG) can be a stability and security threat. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Siemens Desigo PX Web modules PXA40-W0, PXA40-W1, PXA40-W2 for Desigo PX automation controllers PXC00-E.D, PXC50-E.D, PXC100-E.D, PXC200-E.D (All firmware versions < V6.00.046) and Desigo PX Web modules PXA30-W0, PXA30-W1, PXA30-W2 for Desigo PX automation controllers PXC00-U, PXC64-U, PXC128-U (All firmware versions < V6.00.046) use a pseudo random number generator with insufficient entropy to generate certificates for HTTPS, potentially allowing remote attackers to reconstruct the corresponding private key.

The weakness was published 12/23/2016 (Website). The advisory is available at securityfocus.com. This vulnerability is traded as CVE-2016-9154. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. The technical details are unknown and an exploit is not available. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 10/12/2022).
