Objective-C:
Vulnerable Code:
C:
- (void)URLSession:(NSURLSession *)session didReceiveChallenge:(NSURLAuthenticationChallenge *)challenge completionHandler:(void (^)(NSURLSessionAuthChallengeDisposition, NSURLCredential *))completionHandler {
NSString *user = @"user";
NSString *pass = @"pass";
NSURLProtectionSpace *space = [challenge protectionSpace];
if ([space receivesCredentialSecurely] == YES &&
[[space host] isEqualToString:@"myhost.com"] &&
[[space authenticationMethod] isEqualToString:NSURLAuthenticationMethodHTTPBasic]) {
NSURLCredential *credential =
[NSURLCredential credentialWithUser:user
password:pass
persistence:NSURLCredentialPersistenceForSession];
completionHandler(NSURLSessionAuthChallengeUseCredential, credential);
}
}Description: This vulnerable Objective-C code handles HTTP basic authentication with NSURLSession by providing credentials to the server challenge without proper validation of the host and authentication method. It lacks checks for secure transmission and proper host verification, potentially exposing credentials to unauthorized servers.
Patched Code:
C++:
- (void)URLSession:(NSURLSession *)session didReceiveChallenge:(NSURLAuthenticationChallenge *)challenge completionHandler:(void (^)(NSURLSessionAuthChallengeDisposition, NSURLCredential *))completionHandler {
NSString *user = @"user";
NSString *pass = @"pass";
NSURLProtectionSpace *space = [challenge protectionSpace];
if ([space receivesCredentialSecurely] == YES &&
[[space host] isEqualToString:@"myhost.com"] &&
[[space authenticationMethod] isEqualToString:NSURLAuthenticationMethodHTTPBasic]) {
// Verify host and transmission security before providing credentials
if ([self isSecureHost:[space host]] && [self isTransmissionSecure:challenge]) {
NSURLCredential *credential =
[NSURLCredential credentialWithUser:user
password:pass
persistence:NSURLCredentialPersistenceForSession];
completionHandler(NSURLSessionAuthChallengeUseCredential, credential);
} else {
// Reject challenge if host is not secure or transmission is not secure
completionHandler(NSURLSessionAuthChallengeCancelAuthenticationChallenge, nil);
}
} else {
// Reject challenge if not HTTP basic authentication
completionHandler(NSURLSessionAuthChallengeCancelAuthenticationChallenge, nil);
}
}
- (BOOL)isSecureHost:(NSString *)host {
// Implement host verification logic here
// Check if the host is secure (e.g., matches expected domain)
return [host isEqualToString:@"myhost.com"];
}
- (BOOL)isTransmissionSecure:(NSURLAuthenticationChallenge *)challenge {
// Implement transmission security verification logic here
// Check if transmission is secure (e.g., using HTTPS)
return [challenge.protectionSpace.protocol isEqualToString:@"https"];
}Description: The patched Objective-C code enhances security by performing proper validation of the host and transmission security before providing credentials to the server challenge. It checks if the host is secure and if the transmission is over HTTPS, ensuring that credentials are only provided to authorized servers securely.

space.host == "myhost.com" &&
space.authenticationMethod == NSURLAuthenticationMethodHTTPBasic {
let credential = NSURLCredential(user: user, password: pass, persistence: .ForSession)
completionHandler(.UseCredential, credential)
}
