The P1735 IEEE standard describes flawed methods for encrypting electronic-design intellectual property (IP), as well as the management of access rights for such IP, including modification of Rights Block to remove or relax license requirement. The methods are flawed and, in the most egregious cases, enable attack vectors that allow recovery of the entire underlying plaintext IP. Implementations of IEEE P1735 may be weak to cryptographic attacks that allow an attacker to obtain plaintext intellectual property without the key, among other impacts.
Conclusion & alert: CVE-2017-13097 is rated Low Risk (39.9/100): CVSS High severity, with low exploitation likelihood (EPSS 0.10%). Mandatory action: Monitor for updates and reassess as exploit intelligence or EPSS changes.
Risk is dynamic; we continuously reassess and refresh what is shown on this page as upstream context changes.
EPSS lead: Daily EPSS estimates relative likelihood of exploitation; percentile ranks this CVE among scored vulnerabilities (higher = more severe relative rank).

: According to https://www.kb.cert.org/vuls/id/739007: The P1735 IEEE standard describes methods for encrypting electronic-design intellectual property (IP), as well as the management of access rights for such IP. The methods are flawed and, in the most egregious cases, enable attack vectors that allow recovery of the entire underlying plaintext IP. Implementations of IEEE P1735 may be weak to cryptographic attacks that allow an attacker to obtain plaintext intellectual property without the key, among other impacts. <br /> Commercial electronic design automation (EDA) tools that utilize the P1735 standard, or products designed with such EDA tools may be vulnerable. <br /> The CPE configuration provided is likely not inclusive of all vulnerable products. Please contact the vendor of your product for more information.
