Researchers have disclosed a new severe Oracle Cloud Infrastructure (OCI) vulnerability that could be exploited by users to access the virtual disks of other Oracle customers. "Each virtual disk in Oracle's cloud has a unique identifier called OCID," Shir Tamari, head of research at Wiz,  said  in a series of tweets. "This identifier is not considered secret, and organizations do not treat it as such." "Given the OCID of a victim's disk that is not currently attached to an active server or configured as shareable, an attacker could 'attach' to it and obtain read/write over it," Tamari added. The cloud security firm, which dubbed the tenant isolation vulnerability " AttachMe ," said Oracle  patched the issue  within 24 hours of responsible disclosure on June 9, 2022. Accessing a volume using the CLI without sufficient permissions At its core, the vulnerability is rooted in the fact that a disk could be attached to a compute

Earlier this month, Oracle patched a highly critical Java deserialization remote code execution vulnerability in its WebLogic Server component of Fusion Middleware that could allow attackers to easily gain complete control of a vulnerable server. However, a security researcher, who operates through the Twitter handle @pyn3rd and claims to be part of the Alibaba security team, has now found a way using which attackers can bypass the security patch and exploit the WebLogic vulnerability once again. WebLogic Server acts as a middle layer between the front end user interface and the backend database of a multi-tier enterprise application. It provides a complete set of services for all components and handles details of the application behavior automatically. Initially discovered in November last year by Liao Xinxi of NSFOCUS security team, the Oracle WebLogic Server flaw (CVE-2018-2628) can be exploited with network access over TCP port 7001. If exploited successfully, the fl

Follow this real-life network attack simulation, covering 6 steps from Initial Access to Data Exfiltration. See how attackers remain undetected with the simplest tools and why you need multiple choke points in your defense strategy. Surprisingly, most network attacks are not exceptionally sophisticated, technologically advanced, or reliant on zero-day tools that exploit edge-case vulnerabilities. Instead, they often use commonly available tools and exploit multiple vulnerability points. By simulating a real-world network attack, security teams can test their detection systems, ensure they have multiple choke points in place, and demonstrate the value of networking security to leadership. In this article, we demonstrate a real-life attack that could easily occur in many systems. The attack simulation was developed based on the MITRE ATT&CK framework, Atomic Red Team,  Cato Networks ' experience in the field, and public threat intel. In the end, we explain why a holistic secur

Oracle has released a security patch update to address a critical remotely exploitable vulnerability that affects its MICROS point-of-sale (POS) business solutions for the hospitality industry. The fix has been released as part of Oracle's January 2018 update that patches a total of 238 security vulnerabilities in its various products. According to public disclosure by ERPScan, the security firm which discovered and reported this issue to the company, Oracle's MICROS EGateway Application Service, deployed by over 300,000 small retailers and business worldwide, is vulnerable to directory traversal attack. If exploited, the vulnerability ( CVE-2018-2636 ) could allow attackers to read sensitive data and receive information about various services from vulnerable MICROS workstations without any authentication. Using directory traversal flaw, an unauthorized insider with access to the vulnerable application could read sensitive files from the MICROS workstation, includi

Multiple botnets are targeting thousands of publicly exposed and still unpatched Oracle WebLogic servers to deploy crypto miners and steal sensitive information from infected systems. The attacks are taking aim at a recently patched WebLogic Server vulnerability, which was released by Oracle as part of its  October 2020 Critical Patch Update  and subsequently again in November ( CVE-2020-14750 ) in the form of an out-of-band security patch. As of writing, about 3,000 Oracle WebLogic servers are accessible on the Internet-based on stats from the Shodan search engine. Oracle  WebLogic  is a platform for developing, deploying, and running enterprise Java applications in any cloud environment as well as on-premises. The flaw, which is tracked as CVE-2020-14882, has a CVSS score of 9.8 out of a maximum rating of 10 and affects WebLogic Server versions 10.3.6.0.0, 12.1.3.0.0, 12.2.1.3.0, 12.2.1.4.0, and 14.1.1.0.0. Although the issue has been addressed, the release of  proof-of-concep

Almost two years back, Apple introduced Swift programming language at its World Wide Developers Conference (WWDC) to the developers who build software applications for Apple devices. Swift was designed to make it easier for developers to create apps for Apple's mobile platform. Usually developers write complete app code and then compile it to see output, but Swift helps them see results in real time instantly while writing code. Now, reports have been emerged that the search engine giant is also considering making Swift programming language a "first class" language choice for programmers making apps for its Android platform. In between an ongoing legal battle with Oracle over Android, Google is planning to bring Swift into the Android platform with at least two major third-party developers — Facebook and Uber, reports The Next Web. Around the time when Apple officially made Swift an open source language, executives from Google, Facebook and Uber attended a m

Oracle on Tuesday released its quarterly  Critical Patch Update for July 2021  with 342 fixes spanning across multiple products, some of which could be exploited by a remote attacker to take control of an affected system. Chief among them is  CVE-2019-2729 , a critical deserialization vulnerability via XMLDecoder in Oracle WebLogic Server Web Services that's remotely exploitable without authentication. It's worth noting that the weakness was originally addressed as part of an  out-of-band security update  in June 2019. Oracle WebLogic Server is an application server that functions as a platform for developing, deploying, and running enterprise Java-based applications. The flaw, which is rated 9.8 out of a maximum of 10 on the CVSS severity scale, affects WebLogic Server versions 11.1.2.4 and 11.2.5.0 and exists within the Oracle Hyperion Infrastructure Technology. Also fixed in WebLogic Server are six other flaws, three of which have been assigned a CVSS score of 9.8 out

Oracle, other companies hacked by Social Engineering attack in #DefCon 19 A weekend contest from 4th August to 7th August , at the world's largest hacking convention in Las Vegas showed one reason why big corporations seem to be such easy prey for cyber criminals : their workers are poorly trained in security. Reuters post the news about Hacking of Oracle and some more big Companies just by using Social Engineering in DefCon 19. Hackers taking part in the competition on Friday and Saturday found it ridiculously easy in some cases to trick employees at some of the largest U.S. companies to reveal information that can be used in planning cyber attacks against them. A contestant pretended to work for a company's IT department and persuaded an employee to give him information on the configuration of her PC, data that could help a hacker decide what type of malware would work best in an attack. " For me it was a scary call because she was so willing to comply ," said

Oracle suffered with serious vulnerability in the authentication protocol used by some Oracle databases. This Flaw enable a remote attacker to brute-force a token provided by the server prior to authentication and determine a user's password. A researcher - Esteban Martinez Fayo, a researcher with AppSec tomorrow will demonstrate a proof-of-concept attack. Martinez Fayo and his team first reported the bugs to Oracle in May 2010. Oracle fixed it in mid-2011 via the 11.2.0.3 patch set, issuing a new version of the protocol. " But they never fixed the current version, so the current 11.1 and 11.2 versions are still vulnerable ," Martinez Fayo says, and Oracle has no plans to fix the flaws for version 11.1. The first step in the authentication process when a client contacts the database server is for the server to send a session key back to the client, along with a salt. The vulnerability enables an attacker to link a specific session key with a specific password hash. Th

Two critical zero-day vulnerabilities have been discovered in the world's 2nd most popular database management software MySQL that could allow an attacker to take full control over the database. Polish security researcher Dawid Golunski has discovered two zero-days, CVE-2016-6662 and CVE-2016-6663, that affect all currently supported MySQL versions as well as its forked such as MariaDB and PerconaDB. Golunski further went on to publish details and a proof-of-concept exploit code for CVE-2016-6662 after informing Oracle of both issues, along with vendors of MariaDB and PerconaDB. Both MariaDB and PerconaDB had fixed the vulnerabilities, but Oracle had not. The vulnerability (CVE-2016-6662) can be exploited by hackers to inject malicious settings into MySQL configuration files or create their own malicious ones. Exploitation Vector The above flaw could be exploited either via SQL Injection or by hackers with authenticated access to MySQL database (via a network conne

It's time to update your Java program as Oracle has released its massive patch package for multiple security vulnerabilities. The United States software maker Oracle releases its security updates every three months, which it referred to as " Critical Patch Updates " (CPU). Yesterday, Oracle released its second CPU-date of this year providing important updates that include a total of 104 vulnerabilities, the company has announced . From the overall vulnerabilities, 37 security vulnerabilities impact Java SE and several of these flaws are so serious that it can be remotely exploited by a malicious malware to gain system access and execute arbitrary code with the privileges of a local user. Successful exploitation also allows an attacker to manipulate certain local data on a system and can cause a DoS attack without the need of authentication credentials, which means the flaws can be exploited over a network without the need for a username and password to crashin

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on February 2  added  two security flaws to its Known Exploited Vulnerabilities (KEV) Catalog, citing evidence of active exploitation. The first of the two vulnerabilities is  CVE-2022-21587  (CVSS score: 9.8), a critical issue impacting versions 12.2.3 to 12.2.11 of the Oracle Web Applications Desktop Integrator product. "Oracle E-Business Suite contains an unspecified vulnerability that allows an unauthenticated attacker with network access via HTTP to compromise Oracle Web Applications Desktop Integrator," CISA  said . The issue was addressed by Oracle as part of its Critical Patch Update released in October 2022. Not much is known about the nature of the attacks exploiting the vulnerability, but the development follows the publication of a proof-of-concept (PoC) by cybersecurity firm Viettel on January 16, 2023. The second security flaw to be added to the KEV catalog is  CVE-2023-22952  (CVSS score:

Winter is Coming for CentOS 8—but here is how you can enjoy your holidays after all. The server environment is complex and if you're managing thousands of Linux servers, the last thing you want is for an operating system vendor to do something completely unexpected. That is exactly what Red Hat, the parent company of the CentOS Project, did when it suddenly announced a  curtailment of support for CentOS 8  – sending thousands of organizations scrambling for an alternative. In this article, we'll review what happened with CentOS 8 and what it means for users who have already upgraded from CentOS release 7 to release 8. We'll also look at your alternatives for replacing CentOS 8. Finally, we'll do a review of your other option: choosing extended support. Extended lifecycle support (ELS) can reduce the pressure to decide on alternative distribution and it may well be the most practical route for many CentOS 8 users. Official support is critical The difficulties arou

Oracle has released a new patch which kills off a vulnerability in Java 7 that was being exploited by malware developers. " Due to the high severity of these vulnerabilities, Oracle recommends that customers apply this Security Alert as soon as possible ," Eric Maurice, the company's director of software security assurance. The out-of-band Security Alert CVE-2012-4681 includes fixes for "three distinct but related vulnerabilities and one security-in-depth issue" affecting Java running within the browser. Users with vulnerable versions of Java installed can have malware silently planted on their systems just by browsing to a hacked or malicious website unknowingly.Java is a free programming language widely used to enable every day programs and website elements to function, including some games, apps and chat, as well as enterprise apps. The attacks using this vulnerability so far have been Windows-based, the exploit was demonstrated on other platforms supported by Java

The threat actors associated with the  8220 Gang  have been observed exploiting a high-severity flaw in Oracle WebLogic Server to propagate their malware. The security shortcoming is  CVE-2020-14883  (CVSS score: 7.2), a remote code execution bug that could be exploited by authenticated attackers to take over susceptible servers. "This vulnerability allows remote authenticated attackers to execute code using a gadget chain and is commonly chained with  CVE-2020-14882  (an authentication bypass vulnerability also affecting Oracle Weblogic Server) or the use of leaked, stolen, or weak credentials," Imperva  said  in a report published last week. The 8220 Gang has a history of  leveraging known security flaws  to distribute cryptojacking malware. Earlier this May, the group was spotted utilizing another shortcoming in Oracle WebLogic servers (CVE-2017-3506, CVSS score: 7.4) to rope the devices into a crypto mining botnet. Recent attack chains documented by Imperva entail t

Oracle released an emergency patch on Thursday for previously unknown Java vulnerabilities that cybercriminals had targeted with popular exploit kits within hours after the bugs' existence became public, security researchers found yet another vulnerability that can be exploited to run arbitrary code on systems that have the runtime installed. Security researchers from Poland-based security firm Security Explorations claim to have discovered a vulnerability in the Java 7 security update released Thursday that can be exploited to escape the Java sandbox and execute arbitrary code on the underlying system. While so far the vulnerability has only been found being used against Windows, other platforms such as the Mac OS could potentially be targeted through the same exploit. Security Explorations sent a report about the vulnerability to Oracle on Friday together with a proof-of-concept exploit, Adam Gowdiak, the security company's founder and CEO said Friday via email. The compa

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
