ID CVE-2013-7205
Summary Off-by-one error in the process_cgivars function in contrib/daemonchk.c in Nagios Core 3.5.1, 4.0.2, and earlier allows remote authenticated users to obtain sensitive information from process memory or cause a denial of service (crash) via a long string in the last key value in the variable list, which triggers a heap-based buffer over-read.

Exploitability:
CWE CWE-119
CAPEC
  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.
  • Overflow Binary Resource File
    An attack of this type exploits a buffer overflow vulnerability in the handling of binary resources. Binary resources may include music files like MP3, image files like JPEG files, and any other binary file. These attacks may pass unnoticed to the client machine through normal usage of files, such as a browser loading a seemingly innocent JPEG file. This can allow the attacker access to the execution stack and execute arbitrary code in the target process. This attack pattern is a variant of standard buffer overflow attacks using an unexpected vector (binary files) to wrap its attack and open up a new attack vector. The attacker is required to either directly serve the binary content to the victim, or place it in a locale like a MP3 sharing application, for the victim to download. The attacker then is notified upon the download or otherwise locates the vulnerability opened up by the buffer overflow.
  • Buffer Overflow via Symbolic Links
    This type of attack leverages the use of symbolic links to cause buffer overflows. An attacker can try to create or manipulate a symbolic link file such that its contents result in out of bounds data. When the target software processes the symbolic link file, it could potentially overflow internal buffers with insufficient bounds checking.
  • Overflow Variables and Tags
    This type of attack leverages the use of tags or variables from a formatted configuration data to cause buffer overflow. The attacker crafts a malicious HTML page or configuration file that includes oversized strings, thus causing an overflow.
  • Buffer Overflow via Parameter Expansion
    In this attack, the target software is given input that the attacker knows will be modified and expanded in size during processing. This attack relies on the target software failing to anticipate that the expanded data may exceed some internal limit, thereby creating a buffer overflow.
  • Buffer Overflow in an API Call
    This attack targets libraries or shared code modules which are vulnerable to buffer overflow attacks. An attacker who has access to an API may try to embed malicious code in the API function call and exploit a buffer overflow vulnerability in the function's implementation. All clients that make use of the code library thus become vulnerable by association. This has a very broad effect on security across a system, usually affecting more than one software process.
  • Buffer Overflow in Local Command-Line Utilities
    This attack targets command-line utilities available in a number of shells. An attacker can leverage a vulnerability found in a command-line utility to escalate privilege to root.

    description Several issues were corrected in nagios3, a monitoring and management system for hosts, services and networks. CVE-2018-18245 Maximilian Boehner of usd AG found a cross-site scripting (XSS) vulnerability in Nagios Core. This vulnerability allows attackers to place malicious JavaScript code into the web frontend through manipulation of plugin output. In order to do this the attacker needs to be able to manipulate the output returned by nagios checks, e.g. by replacing a plugin on one of the monitored endpoints. Execution of the payload then requires that an authenticated user creates an alert summary report which contains the corresponding output. CVE-2016-9566 It was discovered that local users with access to an account in the nagios group are able to gain root privileges via a symlink attack on the debug log file. CVE-2014-1878 An issue was corrected that allowed remote attackers to cause a stack-based buffer overflow and subsequently a denial of service (segmentation fault) via a long message to cmd.cgi. CVE-2013-7205 | CVE-2013-7108 A flaw was corrected in Nagios that could be exploited to cause a denial of service. This vulnerability is induced due to an off-by-one error within the process_cgivars() function, which can be exploited to cause an out-of-bounds read by sending a specially crafted key value to the Nagios web UI. For Debian 8 'Jessie', these problems have been fixed in version 3.5.1.dfsg-2+deb8u1. We recommend that you upgrade your nagios3 packages. NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Stack-based buffer overflow in the cmd_submitf function in cgi/cmd.c in Nagios Core, possibly 4.0.3rc1 and earlier, and Icinga before 1.8.6, 1.9 before 1.9.5, and 1.10 before 1.10.3 allows remote attackers to cause a denial of service (segmentation fault) via a long message to cmd.cgi. Various command-execution flaws were found in the Snoopy library included with Nagios. These flaws allowed remote attackers to execute arbitrary commands by manipulating Nagios HTTP headers. A privilege escalation flaw was found in the way Nagios handled log files. An attacker able to control the Nagios logging configuration (the 'nagios' user/group) could use this flaw to elevate their privileges to root. Off-by-one error in the process_cgivars function in contrib/daemonchk.c in Nagios Core 3.5.1, 4.0.2, and earlier allows remote authenticated users to obtain sensitive information from process memory or cause a denial of service (crash) via a long string in the last key value in the variable list, which triggers a heap-based buffer over-read. rss-newsfeed.php in Nagios Core 3.4.4, 3.5.1, and earlier, when MAGPIE_CACHE_ON is set to 1, allows local users to overwrite arbitrary files via a symlink attack on /tmp/magpie_cache.
