Attackers who can intercept or originate server responses can construct valid ciphertext under the known key with PKCS#7 padding, enabling the client to accept forged API responses that serve as a prerequisite for further exploitation such as reaching the os.navigateExternal bridge.","cvssScore":5.9,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N","cwes":["CWE-321"],"vendors":[],"products":[],"references":[{"url":"https://gist.github.com/LeoWSY-hashblue/10e5383fc2d4d75faf74a9507c6bba9f","tags":[]},{"url":"https://hr.163.com/product.html/music","tags":[]},{"url":"https://www.vulncheck.com/advisories/netease-cloud-music-weak-encryption-via-eapi-xeapi","tags":[]}],"exploitRefs":[{"url":"https://gist.github.com/LeoWSY-hashblue/10e5383fc2d4d75faf74a9507c6bba9f","tags":[]}],"hasPoc":true,"ai":null}
