Last modified
CVE-2020-13101 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. In OASIS Digital Signature Services (DSS) 1.0, an attacker can control the validation outcome (i.e., trigger either a valid or invalid outcome for a valid or invalid signature) via a crafted XML signature, when the InlineXML option is used. This defeats the expectation of non-repudiation.. EPSS estimates a 0.73% chance of exploitation in the next 30 days.
