{"id":"CVE-2021-32754","state":"PUBLISHED","title":"Improper Restriction of XML External Entity Reference in de.tud.sse","description":"FlowDroid is a data flow analysis tool. FlowDroid versions prior to 2.9.0 contained an XML external entity (XXE) vulnerability that allowed an attacker who had control over the source/sink definition file in XML format to read files from external locations. In order for this to occur, the XML-based format for sources and sinks had to be used and the attacker had to able control the source/sink definition file. The vulnerability was patched in version 2.9.0. As a workaround, do not allow untrusted entities to control the source/sink definition file.","publishedAt":"2021-07-12T23:00:11.000Z","updatedAt":"2024-08-03T23:33:55.825Z","severity":{"score":5.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["secure-software-engineering FlowDroid"],"affected":[{"vendor":"secure-software-engineering","product":"FlowDroid","versions":[{"version":"< 2.9.0","status":"affected"}]}],"references":["https://github.com/secure-software-engineering/FlowDroid/security/advisories/GHSA-39r7-275f-rvgw"],"weaknesses":["CWE-611"],"ingestedAt":"2026-10-29T19:48:33.225Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2021/32xxx/CVE-2021-32754.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2021-32754","state":"PUBLISHED","datePublished":"2021-07-12T23:00:11.000Z","dateUpdated":"2024-08-03T23:33:55.825Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2021-05-12T00:00:00.000Z"},"containers":{"cna":{"title":"Improper Restriction of XML External Entity Reference in de.tud.sse","descriptions":[{"lang":"en","value":"FlowDroid is a data flow analysis tool.
