The vulnerable library exists in Symantec products that run on Microsoft Windows platforms and may be present in OEM versions or other software based on Symantec code. Please see Symantec AntiVirus Decomposition Buffer Overflow (SYM05-027) for further information, including a list of affected products.
A remote attacker could execute arbitrary code or cause a denial of service. Since many scanning processes run with Local System privileges, the attacker could take complete control of a vulnerable system.
In this blog post, we present how our research team approached Zimbra by taking on the perspective of an APT group. As a result, we discovered a 0-day vulnerability in the unrar utility, a 3rd party tool used in Zimbra. The vulnerability ultimately allows a remote attacker to execute arbitrary code on a vulnerable Zimbra instance without requiring any prior authentication or knowledge about it.
The official security patch by RarLab is contained in the UnRar source code version 6.1.7 and is included with the binaries of version 6.12. Any previous version may be vulnerable. Only the Unix binaries (excluding Android) are affected by this vulnerability. WinRAR is free of this bug.
The vulnerable and patched version can differ depending on the Linux distribution you use and from which repository the binaries were downloaded. If you want to make sure that you use a version that includes the security patch, we recommend downloading it directly from RarLab's website.
A Zimbra instance is affected if unrar is installed, which is expected as it is required for spam checking and virus scanning of RAR archives. Due to the way unrar is invoked, it is also expected that RarLab's implementation is installed, which is the vulnerable one.
CVE 2022 37042 is an authentication bypass vulnerability that affects ZCS releases 8.8.15 and 9.0. CVE 2022 37042 could allow an unauthenticated malicious actor access to a vulnerable ZCS instance. According to Zimbra, CVE 2022 37042 is found in the MailboxImportServlet function.[3][4] Zimbra issued fixes in late July 2022.
CVE-2022-30333 is a high-severity directory traversal vulnerability in RARLAB UnRAR on Linux and UNIX allowing a malicious actor to write to files during an extract (unpack) operation. A malicious actor can exploit CVE-2022-30333 against a ZCS server by sending an email with a malicious RAR file. Upon email receipt, the ZCS server would automatically extract the RAR file to check for spam or malware.[5] Any ZCS instance with unrar installed is vulnerable to CVE-2022-30333.
This also includes Zimbra collaboration suite, wherein the vulnerability could lead to pre-authenticated remote code execution on a vulnerable instance, giving the attacker complete access to an email server and even abuse it to access or overwrite other internal resources within the organization's network.
In order to be vulnerable, a user must have a vulnerable version of cpio installed (which researchers said is the case on most systems) and the pax archive utility package must not be installed, as this package is not vulnerable, said researchers. The pax package is installed by default on Ubuntu, so Ubuntu-based Zimbra installations are not vulnerable by default, said researchers; However, they said pax is not installed by default on Red Hat-based distros, making them vulnerable. While further information about the breadth of exploitation is not available, Bowes pointed to instances of exploitation that have been reported in Zimbra support forums.
66. XSS hunter: XSS Hunter allows you to find all kinds of cross-site scripting vulnerabilities, including the often-missed blind XSS. The service works by hosting specialized XSS probes which, upon firing, scan the page and send information about the vulnerable page to the XSS Hunter service.
82. Reconness: ReconNess helps you to run and keep all your #recon in the same place allowing you to focus only on the potentially vulnerable targets without distraction and without requiring a lot of bash skill, or programming skill in general.
The attackers may have identified the vulnerable device themselves by scanning IP addresses. Alternatively, they may have bought a ready-made list containing IP addresses of vulnerable FortiGate VPN Gateway devices. In autumn 2020, an offer to buy a database of such devices appeared on a dark web forum.
The primary causes of the incident include the use of an outdated and vulnerable firmware version on the FortiGate VPN server (version 6.0.2 was used at the time of the attack), which enabled the attackers to exploit the CVE-2018-13379 vulnerability and gain access to the enterprise network.
Are password protected files immune or vulnerable to virus?I constantly password protect my files using winrar. And I noticed that it raises an alarm whenever I will scan it using my antivirus software. Isn't it safe to password protect files?
To make the SQL injection attack process easy, developers have also developed SQL injection tools by creating a good detection engine. With every new release, these tools are becoming smarter. These tools take the vulnerable URL as a parameter and then start attacking the target. Based on its detection and attack engine, these tools are capable of detecting the type of attack. Sometimes, a vulnerable URL is protected via session and requires login. So, these tools have also gotten the capability of login into a web application via provided username and password to perform SQL injection in the target application. These tools can perform GET-based, POST-based or cookie-based SQL injection without any problem.
Mole or (The Mole) is an automatic SQL injection tool available for free. This is an open source project hosted on Sourceforge. You only need to find the vulnerable URL and then pass it in the tool. This tool can detect the vulnerability from the given URL by using Union based or Boolean based query techniques. This tool offers a command line interface, but the interface is easy to use. It also offers auto-completion on both commands and command arguments. So, you can easily use this tool. 781b155fdc
