CVE-2015-1130
CVE-2015-1130 is a security flaw in Apple OS X, the operating system on Macs. Attackers can get into Apple OS X without a valid password. The US Cybersecurity and Infrastructure Security Agency (CISA) added it to its catalog of flaws known to be used in attacks on 10 Feb 2022.[1]
Apple OS X is in things households have, such as phones, computers, browsers and everyday apps, so the fix matters at home as much as at work. Apple has published a fix or advice.
Description
CISA calls it an authentication bypass in Apple OS X. In its words: “The XPC implementation in Admin Framework in Apple OS X before 10.10.3 allows local users to bypass authentication and obtain admin privileges.”[1]
The underlying weakness is CWE-254, in MITRE’s list of common software weaknesses.[2]
It scores 7.8 out of 10 on the Common Vulnerability Scoring System, which rates it high, scored by NVD using CVSS 3.1.[2]
Affected versions
NVD’s record doesn’t list version ranges for it; Apple’s advisory has them[3]. CISA names the product as Apple OS X.
Every device with Apple OS X needs the update.
Exploitation
CISA added it to its catalog of known exploited vulnerabilities on 10 Feb 2022, 2,498 days after it was made public. CISA lists a flaw only when it has reliable evidence of it being exploited, and gave US federal agencies until 10 Aug 2022 to fix it.[1]
FIRST’s Exploit Prediction Scoring System, which estimates how likely a flaw is to be used in attacks in the next 30 days from what it sees across the internet, puts it at 10%. That’s in the top 5% of the flaws it scores.[4]
CISA assesses it as not automatable: each attack takes some work.
CISA doesn’t say who was attacked, or how.
Fix
Apple has published a fix or advice.[3] CISA’s required action: “Apply updates per vendor instructions.”[1]
- Update Apple OS X now.On iPhone and iPad: Settings, General, Software Update. On a Mac: System Settings, General, Software Update. Install it on every Apple device in the house. Then turn on automatic updates, so the next fix arrives on its own.
- If there’s no update, stop using it.CISA’s advice when a flaw being used in attacks has no fix is to stop using the product until it does.
