CVE-2024-43093
CVE-2024-43093 is a security flaw in Android Framework, Google’s operating system for phones and tablets. Someone who already has a foothold can use Android Framework to take full control of the machine. The US Cybersecurity and Infrastructure Security Agency (CISA) added it to its catalog of flaws known to be used in attacks on 7 Nov 2024.[1]
Android Framework is in things households have, such as phones, computers, browsers and everyday apps, so the fix matters at home as much as at work. Android has published a fix or advice.
Description
CISA calls it a privilege escalation in Android Framework. In its words: “Android Framework contains an unspecified vulnerability that allows for privilege escalation.”[1]
The CVE record adds: “In shouldHideDocument of ExternalStorageProvider.java, there is a possible bypass of a file path filter designed to prevent access to sensitive directories due to incorrect unicode normalization. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is needed for exploitation.”[2]
The underlying weakness is CWE-176, in MITRE’s list of common software weaknesses.
It scores 7.3 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; Android’s advisory has them[3]. CISA names the product as Android Framework.
Every device with Android Framework needs the update.
Exploitation
CISA added it to its catalog of known exploited vulnerabilities on 7 Nov 2024. CISA lists a flaw only when it has reliable evidence of it being exploited, and gave US federal agencies until 28 Nov 2024 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 under 1%. That’s in the top 47% 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
Android has published a fix or advice.[3] CISA’s required action: “Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.”[1]
- Update Android Framework now.On Android: Settings, then System or Software update. Phones only get these fixes while their maker still supports them. 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.
