CVE-2015-0310
CVE-2015-0310 is a security flaw in Adobe Flash Player, Adobe’s discontinued browser plug-in for animation and video. Attackers are using a flaw in Adobe Flash Player that its maker hasn't described in detail. The US Cybersecurity and Infrastructure Security Agency (CISA) added it to its catalog of flaws known to be used in attacks on 25 May 2022.[1]
Adobe Flash Player is in things households have, such as phones, computers, browsers and everyday apps, so the fix matters at home as much as at work.
Description
CISA calls it an ASLR bypass in Adobe Flash Player. In its words: “Adobe Flash Player does not properly restrict discovery of memory addresses, which allows attackers to bypass the address space layout randomization (ASLR) protection mechanism.”[1]
The CVE record adds: “Adobe Flash Player before 13.0.0.262 and 14.x through 16.x before 16.0.0.287 on Windows and OS X and before 11.2.202.438 on Linux does not properly restrict discovery of memory addresses, which allows attackers to bypass the ASLR protection mechanism on Windows, and have an unspecified impact on other platforms, via unknown vectors, as exploited in the wild in January 2015.”[2]
The underlying weakness is permissions and access control (CWE-264), in MITRE’s list of common software weaknesses.
It scores 7.8 out of 10 on the Common Vulnerability Scoring System, which rates it high, scored by the organisation that published the CVE using CVSS 3.1.[2]
Affected versions
NVD’s record doesn’t list version ranges for it. CISA names the product as Adobe Flash Player.
Every device with Adobe Flash Player needs the update.
Exploitation
CISA added it to its catalog of known exploited vulnerabilities on 25 May 2022, 2,679 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 15 Jun 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 15%. That’s in the top 4% of the flaws it scores.[3]
CISA assesses it as not automatable: each attack takes some work.
CISA doesn’t say who was attacked, or how.
Fix
CISA’s required action: “The impacted product is end-of-life and should be disconnected if still in use.”[1]
- Update Adobe Flash Player now.Install the latest update from Adobe on every device that has it, and restart when asked. 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.
