With the release of the Microsoft security bulletins for December 2012, Company flag total 7 updates for Windows users, where one is rated as critical that could lead to remote code execution, where as other two are rated as important which fix flaws that could result in the operating system's security features being bypassed. All of the IE fixes involve use-after-free memory vulnerabilities. Where as kernel level exploits bundled into mass-exploitation kits is like Blackhole. In addition to IE, Microsoft is fixing a critical flaw in Microsoft Word that could enable attackers to execute remote code. The vulnerability could be exploited by way of a malformed Rich Text Format (RTF) document. Also Fonts can also be used as a potential attack vector, as this Patch Tuesday reveals.

March 13, 2015Swati Khandelwal
After the latest Microsoft Patch Tuesday updates that came with important patches for Stuxnet and FREAK encryption-downgrade attack , now its time to update your Adobe Flash Player. Adobe has rolled-out an update for its popular Flash Player software that patches a set of 11 critical security vulnerabilities in its program, most of which potentially allow hackers to remotely execute arbitrary code on vulnerable systems. AFFECTED SOFTWARE All versions prior to the latest version 17.0.0.134 of the Flash Player are affected on Windows and Mac OS X machines. Therefore, Adobe Flash Player installed with Google Chrome, as well as Internet Explorer 10 and 11 on Windows 8 and Windows 8.1, should automatically update to the newest version 17.0.0.134.

September 09, 2013Wang Wei
This Tuesday, Microsoft will be releasing its September's Patch Tuesday updates includes 14 bulletins in total, fixing issues in Windows, Office, Outlook, Internet Explorer, SharePoint and FrontPage. In all, there are eight remote code execution flaws in Microsoft Office, Microsoft Server Software, Microsoft Windows, which can allow hackers to gain access to, or take control of an affected system without user prompts or permission. The four critical bulletins affect Sharepoint, Outlook, Internet Explorer and XP and Windows 2003. Bulletien second will address a Remote Code Execution flaw in Microsoft Office that can be triggered simply by previewing an email in Outlook, even without explicitly opening the e-mail. The problem for users is that Outlook automatically displays the content of each email it previews. The remaining 10 bulletins are all rated important by Microsoft, four of them patch remote code execution flaws in Office, while three other privilege escalati
Android Stagefright Exploit Code Released

Android Stagefright Exploit Code Released

September 11, 2015Khyati Jain
Zimperium Mobile Security Labs (zLabs) have been working hard to make Android operating system more safe and secure to use. Zimperium team has publicly released the CVE-2015-1538 Stagefright Exploit , demonstrating the process of Remote Code Execution (RCE) by an attacker. The released exploit is a python code creating an MP4 exploiting the 'stsc' vulnerability dubbed Stagefright. The purpose behind the release is to put penetration testers and security researchers to test and check the vulnerability of the code and analyze the results. Considered as the most critical flaw among all the existing vulnerabilities; the Stagefright flaw is capable of revealing user's information remotely by injecting malicious code, even without any involvements of the user. Two months ago, Zimperium Labs uncovered multiple vulnerabilities in 'libstagefright,' a service attached with the software-based codecs natively in Android smartphones for media playback. The vulnera

Threat actors are actively carrying out opportunistic  scanning  and  exploitation  of Exchange servers using a new exploit chain leveraging a trio of flaws affecting on-premises installations, making them the latest set of bugs after ProxyLogon vulnerabilities were exploited en masse at the start of the year. The remote code execution flaws have been collectively dubbed "ProxyShell." At least 30,000 machines are affected by the vulnerabilities,  according  to a Shodan scan performed by Jan Kopriva of SANS Internet Storm Center. "Started to see in the wild exploit attempts against our honeypot infrastructure for the Exchange ProxyShell vulnerabilities," NCC Group's Richard Warren  tweeted , noting that one of the intrusions resulted in the deployment of a "C# aspx webshell in the /aspnet_client/ directory." Patched in early March 2021,  ProxyLogon  is the moniker for CVE-2021-26855, a server-side request forgery vulnerability in Exchange Server tha

Yahoo-owned Flickr , one of the biggest online photo management and sharing website in the world was recently impacted by critical web application vulnerabilities, which left website's database and server vulnerable hackers. Ibrahim Raafat , a security researcher from Egypt has found SQL injection vulnerabilities on  Flickr Photo Books , new feature for printing custom photo books through Flickr that was launched 5 months ago. He claimed to have found two parameters ( page_id , items ) vulnerable to Blind SQL injection and one  (i.e. order_id ) Direct SQL Injection that allowed him to query the Flickr database for its content by the injection of a SQL SELECT statements. A Successful SQL exploitation could allow an attacker to steal the Database and MYSQL administrator password. Furthermore, Flickr's SQL injection flaws also facilitate the attacker to exploit remote code execution on the server and using  load_file("/etc/passwd")   function he was successfu

Top 30 Critical Security Vulnerabilities Most Exploited by Hackers

July 29, 2021Ravie Lakshmanan
Intelligence agencies in Australia, the U.K., and the U.S. issued a joint advisory on Wednesday detailing the most exploited vulnerabilities in 2020 and 2021, once again demonstrating how threat actors are able to swiftly weaponize publicly disclosed flaws to their advantage. "Cyber actors continue to exploit publicly known—and often dated—software vulnerabilities against broad target sets, including public and private sector organizations worldwide," the U.S. Cybersecurity and Infrastructure Security Agency (CISA), the Australian Cyber Security Centre (ACSC), the United Kingdom's National Cyber Security Centre (NCSC), and the U.S. Federal Bureau of Investigation (FBI)  noted . "However, entities worldwide can mitigate the vulnerabilities listed in this report by applying the available patches to their systems and implementing a centralized patch management system." The top 30 vulnerabilities span a wide range of software, including remote work, virtual pri

Ransomware Gangs Exploiting Windows Print Spooler Vulnerabilities

August 13, 2021Ravie Lakshmanan
Ransomware operators such as Magniber and Vice Society are actively exploiting vulnerabilities in Windows Print Spooler to compromise victims and spread laterally across a victim's network to deploy file-encrypting payloads on targeted systems. "Multiple, distinct threat actors view this vulnerability as attractive to use during their attacks and may indicate that this vulnerability will continue to see more widespread adoption and incorporation by various adversaries moving forward," Cisco Talos  said  in a report published Thursday, corroborating an  independent analysis  from CrowdStrike, which observed instances of Magniber ransomware infections targeting entities in South Korea. While Magniber ransomware was first spotted in late 2017 singling out victims in South Korea through malvertising campaigns, Vice Society is a new entrant that emerged on the ransomware landscape in mid-2021, primarily targeting public school districts and other educational institutions.
