ID Product Version Vulnerability
SUID-2019-00001 Scytl Secure Vote (sVote) 2.1 Jackson-Databind RCE
*SUID-ID's are referencing security issues and bad practices that are not neccessarly exploitable but still might cause issues in certain scenarios.


When checking the online-voting-mixing component we see a vulnerable jackson version imported (evoting-solution-master/source-code/online-voting-mixing/pom.xml):

This version has over 10 CVE's registered:

Those include RCE's:
FasterXML jackson-databind before, 2.8.x before and 2.9.x before 2.9.5 allows unauthenticated remote code execution because of an incomplete fix for the CVE-2017-7525 deserialization flaw. This is exploitable by sending maliciously crafted JSON input to the readValue method of the ObjectMapper, bypassing a blacklist that is ineffective if the c3p0 libraries are available in the classpath.

Which can be exploited fairly simply:
Even though this transitive permission is superseded by other projects it still makes sense to reduce external libraries and upgrade it if possible to reduce risk of mistakes.
