Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Symlink Attack An attacker positions a symbolic link in such a manner that the targeted user or application accesses the link's endpoint, assuming that it is accessing a file with the link's name. The endpoint file may be either output or input. If the file is output, the result is that the endpoint is modified, instead of a file at the intended location. Modifications to the endpoint file may include appending, overwriting, corrupting, changing permissions, or other modifications. In some variants of this attack the attacker may be able to control the change to a file while in other cases they cannot. The former is especially damaging since the attacker may be able to grant themselves increased privileges or insert false information, but the latter can also be damaging as it can expose sensitive information or corrupt or destroy vital system or application files. Alternatively, the endpoint file may serve as input to the targeted application. This can be used to feed malformed input into the target or to cause the target to process different information, possibly allowing the attacker to control the actions of the target or to cause the target to expose information to the attacker. Moreover, the actions taken on the endpoint file are undertaken with the permissions of the targeted user or application, which may exceed the permissions that the attacker would normally have.
- Accessing, Modifying or Executing Executable Files An attack of this type exploits a system's configuration that allows an attacker to either directly access an executable file, for example through shell access; or in a possible worst case allows an attacker to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.
- Leverage Executable Code in Non-Executable Files An attack of this type exploits a system's trust in configuration and resource files, when the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high. The attack can be directed at a client system, such as causing buffer overrun through loading seemingly benign image files, as in Microsoft Security Bulletin MS04-028 where specially crafted JPEG files could cause a buffer overrun once loaded into the browser. Another example targets clients reading pdf files. In this case the attacker simply appends javascript to the end of a legitimate url for a pdf (http://www.gnucitizen.org/blog/danger-danger-danger/) http://path/to/pdf/file.pdf#whatever_name_you_want=javascript:your_code_here The client assumes that they are reading a pdf, but the attacker has modified the resource and loaded executable javascript into the client's browser process. The attack can also target server processes. The attacker edits the resource or configuration file, for example a web.xml file used to configure security permissions for a J2EE app server, adding role name "public" grants all users with the public role the ability to use the administration functionality. The server trusts its configuration file to be correct, but when they are manipulated, the attacker gains full control.
- Manipulating Input to File System Calls An attacker manipulates inputs to the target software which the target software passes to file system calls in the OS. The goal is to gain access to, and perhaps modify, areas of the file system that the target software did not intend to be accessible.

Chris (Matasano Security) reported that Opera may crash if it is redirected by a malicious page to a specially crafted address (CVE-2008-4694). Nate McFeters reported that Opera runs Java applets in the context of the local machine, if that applet has been cached and a page can predict the cache path for that applet and load it from the cache (CVE-2008-4695). Roberto Suggi Liverani (Security-Assessment.com) reported that Opera's History Search results does not escape certain constructs correctly, allowing for the injection of scripts into the page (CVE-2008-4696). David Bloom reported that Opera's Fast Forward feature incorrectly executes scripts from a page held in a frame in the outermost page instead of the page the JavaScript URL was located (CVE-2008-4697). David Bloom reported that Opera does not block some scripts when previewing a news feed (CVE-2008-4698). Opera does not correctly sanitize content when certain parameters are passed to Opera's History Search, allowing scripts to be injected into the History Search results page (CVE-2008-4794). Opera's links panel incorrectly causes scripts from a page held in a frame to be executed in the outermost page instead of the page where the URL was located (CVE-2008-4795). Impact : These vulnerabilities allow remote attackers to execute arbitrary code, to run scripts injected into Opera's History Search with elevated privileges, to inject arbitrary web script or HTML into web pages, to manipulate the address bar, to change Opera's preferences, to determine the validity of local filenames, to read cache files, browsing history, and subscribed feeds or to conduct other attacks.

NASL family Windows NASL id OPERA_960.NASL description The version of Opera installed on the remote host is earlier than 9.60 and thus reportedly affected by several issues : - Specially crafted URLs can cause Opera to crash or allow arbitrary code execution. - Once a Java applet has been cached, a page that can predict the cache path for that applet can load it from cache thereby causing it to run in the security context of the local machine, allowing for reading of other files from the cache. last seen 2020-06-01 modified 2020-06-02 plugin id 34368 published 2008-10-08 reporter This script is Copyright (C) 2008-2018 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/34368 title Opera < 9.60 Multiple Vulnerabilities NASL family FreeBSD Local Security Checks NASL id FREEBSD_PKG_FB84D5DD952811DD9A00001999392805.NASL description Opera reports : If a malicious page redirects Opera to a specially crafted address (URL), it can cause Opera to crash. Given sufficient address content, the crash could cause execution of code controlled by the attacking page. Once a Java applet has been cached, if a page can predict the cache path for that applet, it can load the applet from the cache, causing it to run in the context of the local machine. This allows it to read other cache files on the computer or perform other normally more restrictive actions. These files could contain sensitive information, which could then be sent to the attacker. last seen 2020-06-01 modified 2020-06-02 plugin id 34382 published 2008-10-10 reporter This script is Copyright (C) 2008-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/34382 title FreeBSD : opera -- multiple vulnerabilities (fb84d5dd-9528-11dd-9a00-001999392805)
