CWE-ID: CWE-284 - Improper Access Control

Exploit availability: No

Description

The vulnerability allows a local application to gain access to sensitive information.

The vulnerability exists due to improper access restrictions in AppleMobileFileIntegrity. A local application can gain access to sensitive user information.

Mitigation

Install update from vendor's website.

Vulnerable software versions

macOS: 11.0 20A2411 - 11.7.2 20G1020


CPE2.3 External links

http://support.apple.com/en-us/HT213603

Q & A

Can this vulnerability be exploited remotely?

Is there known malware, which exploits this vulnerability?

2) Input validation error

EUVDB-ID: #VU66881

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2022-35252

CWE-ID: CWE-20 - Improper Input Validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to the way curl handles cookies with control codes (byte values below 32). When cookies that contain such control codes are later sent back to an HTTP(S) server, it might make the server return a 400 response, effectively allowing a "sister site" to deny service to siblings.

Mitigation

Install update from vendor's website.
