NONE Summary
WKWebView in WebKit in Apple iOS before 10, iTunes before 12.5.1 on Windows, and Safari before 10 does not properly verify X.509 certificates from HTTPS servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.
Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Signature Spoofing by Key Recreation An attacker obtains an authoritative or reputable signer's private signature key by exploiting a cryptographic weakness in the signature algorithm or pseudorandom number generation and then uses this key to forge signatures from the original signer to mislead a victim into performing actions that benefit the attacker.
Nessus
NASL family Peer-To-Peer File Sharing NASL id ITUNES_12_5_1_BANNER.NASL description The version of Apple iTunes running on the remote Windows host is prior to 12.5.1. It is, therefore, affected by multiple vulnerabilities : - A remote code execution vulnerability exists due to improper handling of error prototypes. An unauthenticated, remote attacker can exploit this, by convincing a user to visit a maliciously crafted website, to execute arbitrary code. (CVE-2016-4728) - An information disclosure vulnerability exists in WebKit due to a permission issue caused by improper handling of the location variable. An unauthenticated, remote attacker can exploit this, by convincing a user to visit a maliciously crafted website, to disclose sensitive information. (CVE-2016-4758) - Multiple memory corruption errors exist in WebKit due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit these issues, by convincing a user to visit a maliciously crafted website, to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-4759, CVE-2016-4762, CVE-2016-4764, CVE-2016-4765, CVE-2016-4766, CVE-2016-4767, CVE-2016-4768, CVE-2016-4769) - A rebinding flaw exists in WebKit due to a failure to restrict HTTP/0.9 responses to default ports and cancel resource loads if a document is loaded with a different HTTP protocol version. An unauthenticated, remote attacker can exploit this, by convincing a user to visit a maliciously crafted website, to access non-HTTP services. (CVE-2016-4760) - A security bypass vulnerability exists in WebKit in the WKWebView component due to a failure to properly verify X.509 certificates from HTTPS servers. A man-in-the-middle attacker can exploit this, via a specially crafted certificate, to spoof servers and disclose or manipulate network traffic.
