CVE-2015-1187
CVE-2015-1187 is a security flaw in D-Link and TRENDnet Multiple Devices, routers for homes and small offices. Attackers can run their own code on D-Link and TRENDnet Multiple Devices. The US Cybersecurity and Infrastructure Security Agency (CISA) added it to its catalog of flaws known to be used in attacks on 25 Mar 2022.[1]
D-Link and TRENDnet Multiple Devices is in things households have: home and small-office routers, so the fix matters at home as much as at work.
Description
CISA calls it a remote code execution in D-Link and TRENDnet Multiple Devices. In its words: “The ping tool in multiple D-Link and TRENDnet devices allow remote attackers to perform remote code execution.”[1]
The underlying weakness is improper authentication (CWE-287), in MITRE’s list of common software weaknesses.[2]
It scores 9.8 out of 10 on the Common Vulnerability Scoring System, which rates it critical, scored by NVD using CVSS 3.1.[2]
Affected versions
NVD’s record doesn’t list version ranges for it. CISA names the product as D-Link and TRENDnet Multiple Devices.
Every device with D-Link and TRENDnet Multiple Devices needs the update.
Exploitation
CISA added it to its catalog of known exploited vulnerabilities on 25 Mar 2022, 1,646 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 Apr 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 83%. That’s in the top 1% of the flaws it scores.[3]
CISA assesses it as automatable: attackers can run it against many targets at once.
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 D-Link and TRENDnet Multiple Devices now.Open the router’s app, or its admin page in a browser, and look for a firmware update. Then turn on automatic updates, so the next fix arrives on its own.
- If the maker has stopped updating it, replace it.Routers stop getting fixes after a few years, and attackers keep a list of the ones that did. If there’s no newer firmware, it won’t be fixed.
