CVE-2024-54017

The SIPROTEC 5 devices do not use sufficiently random numbers to generate session identifiers. This could facilitate a brute-force attack against a valid session identifier which could allow an unauthenticated remote attacker to hijack a valid user session. The affected session identifiers are only used in a subset of the endpoints that are provided by the affected products. Siemens is preparing fix versions and recommends countermeasures for products where fixes are not, or not yet available. The following versions of Siemens SIPROTEC 5 are affected: SIPROTEC 5 6MD84 (CP300) vers:intdot/SIPROTEC 5 6MD85 (CP200) vers:all/* () SIPROTEC 5 6MD85 (CP300) vers:intdot/>=7.80|SIPROTEC 5 6MD86 (CP200) vers:all/* () SIPROTEC 5 6MD86 (CP300) vers:intdot/>=7.80|SIPROTEC 5 6MD89 (CP300) vers:intdot/>=7.80|SIPROTEC 5 6MU85 (CP300) vers:intdot/>=7.80|SIPROTEC 5 7KE85 (CP200) vers:all/* () SIPROTEC 5 7KE85 (CP300) vers:intdot/>=7.80|SIPROTEC 5 7SA82 (CP100) vers:intdot/>=7.80 (CVE-2024-54017) SIPROTEC 5 7SA82 (CP150) vers:intdot/SIPROTEC 5 7SA84 (CP200) vers:all/* () SIPROTEC 5 7SA86 (CP200) vers:all/* () SIPROTEC 5 7SA86 (CP300) vers:intdot/>=7.80|SIPROTEC 5 7SA87 (CP200) vers:all/* () SIPROTEC 5 7SA87 (CP300) vers:intdot/>=7.80|SIPROTEC 5 7SD82 (CP100) vers:intdot/>=7.80 (CVE-2024-54017) SIPROTEC 5 7SD82 (CP150) vers:intdot/SIPROTEC 5 7SD84 (CP200) vers:all/* () SIPROTEC 5 7SD86 (CP200) vers:all/* () SIPROTEC 5 7SD86 (CP300) vers:intdot/>=7.80|SIPROTEC 5 7SD87 (CP200) vers:all/* () SIPROTEC 5 7SD87 (CP300) vers:intdot/>=7.80|SIPROTEC 5 7SJ81 (CP100) vers:intdot/>=7.80 (CVE-2024-54017) SIPROTEC 5 7SJ81 (CP150) vers:intdot/SIPROTEC 5 7SJ82 (CP100) vers:intdot/>=7.80 (CVE-2024-54017) SIPROTEC 5 7SJ82 (CP150) vers:intdot/SIPROTEC 5 7SJ85 (CP200) vers:all/* () SIPROTEC 5 7SJ85 (CP300) vers:intdot/>=7.80|SIPROTEC 5 7SJ86 (CP200) vers:all/* () SIPROTEC 5 7SJ86 (CP300) vers:intdot/>=7.80|SIPROTEC 5 7SK82 (CP100) vers:intdot/>=7.80 (CVE-2024-54017) SIPROTEC 5 7SK82 (CP150) vers:intdot/SIPROTEC 5 7SK85 (CP200) vers:all/* () SIPROTEC 5 7SK85 (CP300) vers:intdot/>=7.80|SIPROTEC 5 7SL82 (CP100) vers:intdot/>=7.80 (CVE-2024-54017) SIPROTEC 5 7SL82 (CP150) vers:intdot/SIPROTEC 5 7SL86 (CP200) vers:all/* () SIPROTEC 5 7SL86 (CP300) vers:intdot/>=7.80|SIPROTEC 5 7SL87 (CP200) vers:all/* () SIPROTEC 5 7SL87 (CP300) vers:intdot/>=7.80|SIPROTEC 5 7SS85 (CP200) vers:all/* () SIPROTEC 5 7SS85 (CP300) vers:intdot/>=7.80|SIPROTEC 5 7ST85 (CP200) vers:all/* () SIPROTEC 5 7ST85 (CP300) vers:intdot/>=7.80|SIPROTEC 5 7ST86 (CP300) vers:intdot/SIPROTEC 5 7SX82 (CP150) vers:intdot/SIPROTEC 5 7SX85 (CP300) vers:intdot/SIPROTEC 5 7SY82 (CP150) vers:intdot/SIPROTEC 5 7UM85 (CP300) vers:intdot/>=7.80|SIPROTEC 5 7UT82 (CP100) vers:intdot/>=7.80 (CVE-2024-54017) SIPROTEC 5 7UT82 (CP150) vers:intdot/SIPROTEC 5 7UT85 (CP200) vers:all/* () SIPROTEC 5 7UT85 (CP300) vers:intdot/>=7.80|SIPROTEC 5 7UT86 (CP200) vers:all/* () SIPROTEC 5 7UT86 (CP300) vers:intdot/>=7.80|SIPROTEC 5 7UT87 (CP200) vers:all/* () SIPROTEC 5 7UT87 (CP300) vers:intdot/>=7.80|SIPROTEC 5 7VE85 (CP300) vers:intdot/>=7.80|SIPROTEC 5 7VK87 (CP200) vers:all/* () SIPROTEC 5 7VK87 (CP300) vers:intdot/>=7.80|SIPROTEC 5 7VU85 (CP300) vers:intdot/SIPROTEC 5 Compact 7SX800 (CP050) vers:intdot/ CVSS Vendor Equipment Vulnerabilities v3 5.3 Siemens Siemens SIPROTEC 5 Small Space of Random Values Background Critical Infrastructure Sectors: Critical Manufacturing Countries/Areas Deployed: Worldwide Company Headquarters Location: Germany
