Over 199,500 Websites Are Still Vulnerable to Heartbleed OpenSSL Bug

Over 199,500 Websites Are Still Vulnerable to Heartbleed OpenSSL Bug

January 23, 2017Swati Khandelwal
It's more than two and half years since the discovery of the critical OpenSSL Heartbleed vulnerability , but the flaw is still alive as it appears that many organizations did not remediate properly to the serious security glitch. It was one of the biggest flaws in the Internet's history that affected the core security of as many as two-thirds of the world's servers i.e. half a million servers at the time of its discovery in April 2014. However, the critical bug still affects more than 199,500 systems even after 2 years and 9 months have already passed, according to a new report published today on Shodan, a search engine that scans for vulnerable devices. Over 199,500 Systems Still Vulnerable to Heartbleed Heartbleed (CVE-2014-0160) was a serious bug in the OpenSSL's implementation of the TLS/DTLS heartbeat extension that allowed attackers to read portions of the affected server’s memory, potentially revealing users data that the server isn't intended to re
OpenSSL Releases Patch For "High" Severity Vulnerability

OpenSSL Releases Patch For "High" Severity Vulnerability

November 10, 2016Mohit Kumar
As announced on Tuesday, the OpenSSL project team released OpenSSL version 1.1.0c that addresses three security vulnerabilities in its software. The most serious of all is a heap-based buffer overflow bug (CVE-2016-7054) related to Transport Layer Security (TLS) connections using *-CHACHA20-POLY1305 cipher suites. The vulnerability, reported by Robert Święcki of the Google Security Team on September 25, can lead to DoS attack by corrupting larger payloads, resulting in a crash of OpenSSL. The severity of the flaw is rated "High" and does not affect OpenSSL versions prior to 1.1.0. However, the OpenSSL team reports there is no evidence that the flaw is exploitable beyond a DoS attack. The OpenSSL project also patches a moderate severity flaw (CVE-2016-7053) that can cause applications to crash. "Applications parsing invalid CMS structures can crash with a NULL pointer dereference. This is caused by a bug in the handling of the ASN.1 CHOICE type in OpenSSL 1.1.0

Critical DoS Flaw found in OpenSSL — How It Works

September 23, 2016Swati Khandelwal
The OpenSSL Foundation has patched over a dozen vulnerabilities in its cryptographic code library, including a high severity bug that can be exploited for denial-of-service (DoS) attacks. OpenSSL is a widely used open-source cryptographic library that provides encrypted Internet connections using Secure Sockets Layer (SSL) or Transport Layer Security (TLS) for the majority of websites, as well as other secure services. The vulnerabilities exist in OpenSSL versions 1.0.1, 1.0.2 and 1.1.0 and patched in OpenSSL versions 1.1.0a, 1.0.2i and 1.0.1u. The Critical-rated bug ( CVE-2016-6304 ) can be exploited by sending a large OCSP Status Request extension on the targeted server during connection negotiations, which causes memory exhaustion to launch DoS attacks, the OpenSSL Project said . What is OCSP Protocol? OCSP (Online Certificate Status Protocol), supported by all modern web browsers, is a protocol designed to perform verification and obtain the revocation status of a digital

May 05, 2016Mohit Kumar
OpenSSL has released a series of patches against six vulnerabilities, including a pair of high-severity flaws that could allow attackers to execute malicious code on a web server as well as decrypt HTTPS traffic . OpenSSL is an open-source cryptographic library that is the most widely being used by a significant portion of the Internet services; to cryptographically protect their sensitive Web and e-mail traffic using the Secure Sockets Layer (SSL) or Transport Layer Security (TLS) protocol. One of the high-severity flaws, CVE-2016-2107 , allows a man-in-the-middle attacker to initiate a " Padding Oracle Attack " that can decrypt HTTPS traffic if the connection uses AES-CBC cipher and the server supports AES-NI. A Padding Oracle flaw weakens the encryption protection by allowing attackers to repeatedly request plaintext data about an encrypted payload content. The Padding Oracle flaw ( exploit code ) was discovered by Juraj Somorovsky using his own developed tool c

DROWN Attack — More than 11 Million OpenSSL HTTPS Websites at Risk

March 01, 2016Swati Khandelwal
A new deadly security vulnerability has been discovered in OpenSSL that affects more than 11 Million modern websites and e-mail services protected by an ancient, long deprecated transport layer security protocol, Secure Sockets Layer (SSLv2). Dubbed DROWN , the highly critical security hole in OpenSSL was disclosed today as a low-cost attack that could decrypt your sensitive, secure HTTPS communications, including passwords and credit card details… ...and that too in a matter of hours or in some cases almost immediately, a team of 15 security researchers from various universities and the infosec community warned Tuesday. Here’s what the security researchers said: "We've been able to execute the attack against OpenSSL versions that are vulnerable to CVE-2016-0703 in under a minute using a single PC. Even for servers that do not have these particular bugs, the general variant of the attack, which works against any SSLv2 server, can be conducted in under 8 hour

July 09, 2015Mohit Kumar
The mysterious security vulnerability in the widely used OpenSSL code library is neither HeartBleed nor FREAK, but it’s critical enough to be patched by sysadmins without any delay. OpenSSL Foundation released the promised patch against a high severity vulnerability in OpenSSL versions 1.0.1n and 1.0.2b, resolving a certificate forgery issue in the implementations of the crypto protocol. The critical vulnerability could allow man-in-the-middle attackers to impersonate cryptographically protected websites, virtual private networks, or e-mail servers, and snoop on encrypted Internet traffic. The vulnerability, ( CVE-2015-1793 ), is due to a problem lies in the certificate verification process. An error in its implementation skipped some security checks on new, untrusted certificates. By exploiting this vulnerability, an attacker could circumvent certificate warnings that enable them to force applications into treating an invalid certificate as a legitimate Certificat

The open source encryption protocol, OpenSSL, which is used by several social networks, search engines, banks and other websites to enable secure connections while transmitting data, came to everybody's attention following the Heartbleed vulnerability , a critical bug in the OpenSSL's implementation of the TLS/DTLS heartbeat extension that allows attackers to read portions of the affected server’s memory, potentially revealing users data, that the server did not intend to reveal. Now, the biggest Internet giant Google is launching a new fork of OpenSSL, which they dubbed as BoringSSL, developed by its own independent work with the code. " We have used a number of patches on top of OpenSSL for many years, " Adam Langley, a cryptography engineer and Google employee, wrote in a blog post introducing BoringSSL. " Some of them have been accepted into the main OpenSSL repository, but many of them don't mesh with OpenSSL's guarantee of API and ABI

OpenSSL Vulnerable to Man-in-the-Middle Attack and Several Other Bugs

June 05, 2014Mohit Kumar
Remember OpenSSL Heartbleed vulnerability ? Several weeks ago, the exposure of this security bug chilled the Internet, revealed that millions of websites were vulnerable to a flaw in the OpenSSL code which they used to encrypt their communications. Now once again the OpenSSL Foundation has issued software updates to patch six new vulnerabilities, and two of them are critical. MAN-IN-THE-MIDDLE ATTACK (CVE-2014-0224) First critical vulnerability (CVE-2014-0224) in OpenSSL is " CCS Injection " - resides in ChangeCipherSpec (CCS) request sent during the handshake that could allow an attacker to perform a man-in-the-middle attack against the encrypted connection servers and clients.  By exploiting this vulnerability an attacker could intercept an encrypted connection which allows him to decrypt, read or manipulate the data. But the reported flaw is exploitable only if both server and client are vulnerable to this issue. According to the OpenSSL advisory , " An attacker

Beware Of Fake 'HeartBleed Bug Remover Tool', Hijacks System with Malware

May 28, 2014Wang Wei
I am considering that you all must have read my last article on OpenSSL Heartbleed , a critical bug in the OpenSSL's implementation of the TLS/DTLS heartbeat extension that allows attackers to read portions of the affected server’s memory, potentially revealing users data, that the server did not intend to reveal. The Heartbleed vulnerability made headlines around the world and my last article explains everything about probably the biggest Internet vulnerability in recent history, but still some readers are not aware of its nature, otherwise they would not have been a victim of the spam campaigns. Spammers are very smart on gaining from every opportunity they get, so this time they are taking advantage of the infamous Heartbleed bug and frighten the users into installing Anti-Heartbleed Software onto their systems, which is obviously a malware. The researchers at Symantec have unearthed a spam campaign targeting people by sending spam emails that warns them their

300,000 Servers Still Vulnerable to Heartbleed Vulnerability After One Month

May 09, 2014Swati Khandelwal
It’s more than a month since we all were warned of the critical OpenSSL Heartbleed vulnerability , but that doesn't mean it disappeared. The critical bug compromised many popular websites and after been discovered the problem was solved. But is that so? No, not at all! A recent finding from the security researcher Robert David Graham claims that there are still more than 300,000 servers apparently remain vulnerable to the most critical OpenSSL bug, Heartbleed, which is admittedly down in numbers from the previous which resulted in over 600,000 systems a month ago. Graham announced on the Errata Security blog that he arrived at the number through a recently done global internet scan (or at least the important bits: port 443 of IPv4 addresses), which reveals that exactly 318,239 systems are still vulnerable to the OpenSSL Heartbleed bug and over 1.5 million servers still support the vulnerable "heartbeat" feature of OpenSSL that allowed the critical bug. “

April 19, 2014Mohit Kumar
Cyber criminals have explored one more way to exploit Heartbleed OpenSSL bug against organisations to hijack multiple active web sessions conducted over a virtual private network connection. The consulting and incident response Mandiant investigated targeted attack against an unnamed organization and said the hackers have exploited the “ Heartbleed ” security vulnerability in OpenSSL running in the client’s SSL VPN concentrator to remotely access active sessions of an organization's internal network. The incident is the result of attacks leveraging the OpenSSL Heartbleed vulnerabilities, which resides in the OpenSSL’s heartbeat functionality, if enabled would return 64KB of random memory in plaintext to any client or server requesting for a connection. The vulnerability infected almost two-third of internet web servers, including the popular websites. Recently, there has been an arrest of a Canadian teen of stealing usernames, credentials, session IDs and other da

Several Tor Exit Nodes Vulnerable To Heartbleed Bug

April 17, 2014Mohit Kumar
Half of the Internet fall victim to the biggest threat, Heartbleed bug and even the most popular online anonymity network Tor is also not spared from this bug. Tor is one of the best and freely available privacy software, runs on the network of donated servers that lets people communicate anonymously online through a series of nodes that is designed to provide anonymity for users and bypass Internet censorship. When you use the Tor software, your IP address remains hidden and it appears that your connection is coming from the IP address of a Tor exit relay or nodes, which can be anywhere in the world. An Exit relay is the final relay that Tor encrypted traffic passes through before it reaches its destination. But some of these Tor exit nodes are running on the servers with the affected version of OpenSSL installed which are vulnerable to the critical Heartbleed Flaw. This means an attacker can grab the hidden information from the Tor network which is actually restricte
