Free Heartbleed-Checker Released for Firefox Browser

Browser plug-ins arrive for Firefox and Chrome that scan websites for Heartbleed risk

A developer today released a free add-on for Mozilla Firefox that checks websites for vulnerability to the massive Heartbleed flaw. Tom Brennan, founder of ProactiveRISK, says he wrote the tool after getting an overwhelming number of requests from family and friends about how to protect themselves from websites that are vulnerable to Heartbleed. "They just wanted their browser to tell them, like a radar detector," Brennan says. 

The browser plug-in provides color-coding warnings for websites: Red means the site is vulnerable to Heartbleed. Green means it's safe. There's also a yellow warning for sites that may be vulnerable.

"Like a traffic light on the Internet, it is the users' responsibility to be proactive about risk in addition to the sysadmin defender working hard every day to put out the fire of the day," Brennan says.

"The code is open-source and a donation to the community," he says. "And maybe it will stop the phone calls from users asking for suggestions to something they don't control."

A similar tool for Chrome was released yesterday by developer Jamie Hoyle. The Chromebleed Checker add-in for the Chrome browser also warns users of Heartbleed-vulnerable sites.

"Whilst some servers have been patched already, many remain that have not been patched. Chromebleed uses a web service developed by Filippo Valsorda and checks the URL of the page you have just loaded," the Chromebleed description says. "If it is affected by Heartbleed, then a Chrome notification will be displayed."

Valsorda this week released one of the first tools to scan websites for Heartbleed vulnerability. Errata Security did an initial scan this week for vulnerable sites using its masscan tool. Vendors such as Qualys and LastPass have released free website scanners, and there is also a Metasploit module for Heartbleed.

Meanwhile, Apple told news site Recode that IOS and OS X do not use the vulnerable version of SSL and that its "key Web-based services were not affected."

Re: Different Solutions
I second Ryan's question about where other DR community members are in their remediation efforts for Heartbleed. We've collected some data in our online flash poll (see column on the far right or click here). But so far about 65 percent of respondents have installed or in the process of installing the update and 40 percent are replacing digital certificates. 

If you haven't taken the poll, check it out. And also let's talk about what you are (or aren't doing about it) in the the comments.

These checkers are very nifty. From a corporate standpoint, my company ran vulnerability scans to check and see if any of our servers were running the OpenSSL with the HeartBeat extension. What are other methods people have been using and what steps were taken to remediate?

CVE-2021-26788
PUBLISHED: 2021-03-08
Oryx Embedded CycloneTCP 1.7.6 to 2.0.0, fixed in 2.0.2, is affected by incorrect input validation, which may cause a denial of service (DoS). To exploit the vulnerability, an attacker needs to have TCP connectivity to the target system. Receiving a maliciously crafted TCP packet from an unauthentic...

PUBLISHED: 2021-03-08
The package github.com/pires/go-proxyproto before 0.5.0 are vulnerable to Denial of Service (DoS) via the parseVersion1() function. The reader in this package is a default bufio.Reader wrapping a net.Conn. It will read from the connection until it finds a newline. Since no limits are implemented in ...
CVE-2009-20001
PUBLISHED: 2021-03-07
An issue was discovered in MantisBT before 2.24.5. It associates a unique cookie string with each user. This string is not reset upon logout (i.e., the user session is still considered valid and active), allowing an attacker who somehow gained access to a user's cookie to login as them.
CVE-2020-28466

This affects all versions of package github.com/nats-io/nats-server/server. Untrusted accounts are able to crash the server using configs that represent a service export/import cycles. Disclaimer from the maintainers: Running a NATS service which is exposed to untrusted users presents a heightened r...
