PARTIAL Summary
Jenkins before versions 2.44, 2.32.2 is vulnerable to an insufficient permission check for periodic processes (SECURITY-389). The URLs /workspaceCleanup and /fingerprintCleanup did not perform permission checks, allowing users with read access to Jenkins to trigger these background processes (that are otherwise performed daily), possibly causing additional load on Jenkins master and agents.

It is, therefore, affected by the following vulnerabilities : - A DOM-based cross-site scripting (XSS) vulnerability exists in jQuery Core due to improper validation of certain tags while being rendered using innerHTML. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary script code in the user's browser session. (CVE-2011-4969) - An integer overflow condition exists in jBCrypt in the key stretching implementation in gensalt, within the crypt_raw() function, which is triggered when the 'log_rounds' parameter is set to the maximum value (31). An unauthenticated, remote attacker can exploit this to cause log_rounds to perform zero rounds, allowing a brute-force attack to more easily determine the password hash. (CVE-2015-0886) - A cross-site request forgery vulnerability (XSRF) exists due to several URLs related to group and role management not requiring POST form submission. An unauthenticated, remote attacker can exploit this to create unused roles, delete unused roles, and set group descriptions. Note that only Jenkins Enterprise is affected by this issue. (CVE-2016-9887) - A flaw exists when sensitive data, such as passwords, is encrypted using AES-128 with electronic codebook mode (ECB). An authenticated, remote attacker can exploit this to disclose information about reused passwords. (CVE-2017-2598) - An unspecified flaw exists that is triggered when handling new items due to insufficient permission checks. An authenticated, remote attacker can exploit this, by using the name of an already existing item, to create a new item that overwrites the existing item or to gain access to related objects. (CVE-2017-2599) - An information disclosure vulnerability exists due to improper permissions being set for accessing node monitor data via the remote API. An authenticated, remote attacker can exploit this to disclose system configuration and runtime information. (CVE-2017-2600) - A stored cross-site scripting (XSS) vulnerability exists due to improper validation of input to names and descriptions fields before returning it to users. An authenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary script code in a user's browser session. (CVE-2017-2601) - A flaw exists in the Agent-to-Master Security Subsystem because build metadata from the Pipeline suite is not properly blacklisted. An authenticated, remote attacker can exploit this to overwrite metadata files. (CVE-2017-2602) - A flaw exists in the config.xml API when handling user-initiated agent disconnects, which results in User objects being included in the agent API output. An authenticated, remote attacker can exploit this to disclose sensitive information (e.g., user API tokens). (CVE-2017-2603) - A flaw exists when handling permissions for administrative monitors that allows an authenticated, remote attacker to access certain provided actions. (CVE-2017-2604) - A flaw exists in the Re-Key Admin Monitor when re-encrypting secrets with a new key that results in old secrets, including the encryption key, being stored with world-readable permissions. A local attacker can exploit this to disclose sensitive information from the backup files. (CVE-2017-2605) - A flaw exists in the internal API, specifically within the Jenkins::getItems() function, when requesting a list of items via UnprotectedRootAction. An authenticated, remote attacker can exploit this to disclose information regarding otherwise restricted items. (CVE-2017-2606) - A stored cross-site scripting (XSS) vulnerability exists due to improper validation of input passed via serialized console notes before returning it to users in build logs. An authenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary script code in a user's browser session. (CVE-2017-2607) - A flaw exists in the XStream-based API due to improper validation of user-supplied input before it is deserialized. An authenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary code. (CVE-2017-2608) - A flaw exists in the search box implementation due to the autocompletion feature displaying the names of restricted views. An authenticated, remote attacker can exploit this to disclose sensitive names of views. (CVE-2017-2609) - A stored cross-site scripting (XSS) vulnerability exists due to improper validation of input passed in user names before returning it to users. An authenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary script code in a user's browser session. (CVE-2017-2610) - A flaw exists due to improper validation of permissions to the /workspaceCleanup and /fingerprintCleanup URLs. An authenticated, remote attacker can exploit this to cause a high load on the master and agents. (CVE-2017-2611) - A flaw exists due to a failure to properly restrict access to JDK download credentials. An authenticated, remote attacker can exploit this to overwrite the credentials, thereby causing builds to fail. (CVE-2017-2612) - A cross-site request forgery (XSRF) vulnerability exists due to a failure by HTTP GET requests to /user to require multiple steps, explicit confirmation, or a unique token when performing certain sensitive actions. An unauthenticated, remote attacker can exploit this, by convincing a user to follow a specially crafted link, to cause the creation of new temporary users. (CVE-2017-2613) - An information disclosure vulnerability which exists in its re-key admin monitor component due to world readable permissions being set on the directory it creates to store secret information. An unauthenticated, remote attacker can exploit this to disclose information contained in this directory.
