Description
This security bulletin contains information about 20 secuirty vulnerabilities.
1) Inadequate Encryption Strength (CVE-ID: CVE-2023-0361)
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to an error in the TLS RSA key exchange. A remote attacker can perform Bleichenbacher oracle attack and decrypt information.
2) Information disclosure (CVE-ID: CVE-2023-27904)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application within error stack traces related to agents. A remote user can gain unauthorized access to sensitive information on the system.
3) Incorrect default permissions (CVE-ID: CVE-2023-27903)
The vulnerability allows a local user to compromise the target system.
The vulnerability exists due to the affected plugin creates the temporary file in the default temporary directory with the default permissions for newly created files. A local user can read and write the file before it is used in the build.
4) Code Injection (CVE-ID: CVE-2023-27899)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to the affected plugin creates the temporary file in the system temporary directory with the default permissions for newly created files. A remote user can read and write the file before it is installed in Jenkins and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
5) Stored cross-site scripting (CVE-ID: CVE-2023-27898)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data in plugin manager. A remote attacker can inject and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
6) State Issues (CVE-ID: CVE-2023-27535)
The vulnerability allows a remote attacker to gain unauthorized access to FTP server.
The vulnerability exists due to cURL will reuse a previously created FTP connection even when one or more options had been changed that could have made the effective user a very different one. A remote attacker can connect to the FTP server using credentials supplied by another user and gain access to otherwise restricted functionality.
The settings in questions are CURLOPT_FTP_ACCOUNT, CURLOPT_FTP_ALTERNATIVE_TO_USER, CURLOPT_FTP_SSL_CCC and CURLOPT_USE_SSL level.
7) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2023-25725)
The vulnerability allows a remote attacker to perform HTTP request smuggling attacks.
The vulnerability exists due to improper validation of HTTP/1 requests. A remote attacker can send a specially crafted HTTP request with empty fields, which could be used to truncate the list of HTTP headers and thus make some headers disappear after being parsed and processed for HTTP/1.0 and HTTP/1.1
Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.
8) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-24422)
The vulnerability allows a remote attacker to execute arbitrary code on the system.
The vulnerability exists due to a sandbox bypass issue. A remote user can bypass the sandbox protection and execute arbitrary code in the context of the Jenkins controller JVM.
9) OS Command Injection (CVE-ID: CVE-2023-2491)
The vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.
The vulnerability exists due to a missing fix for #VU74578 (CVE-2023-28617). A remote attacker can trick the victim to open a specially crafted file and execute arbitrary OS commands on the target system via a file name or directory name that contains shell metacharacters.
10) Code Injection (CVE-ID: CVE-2022-42889)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to an insecure variable interpolation when processing untrusted input. A remote attacker can send a specially crafted input and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
Note, the vulnerability was dubbed Text4shell.
11) Security features bypass (CVE-ID: CVE-2023-32313)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to the possibility to get a read-write reference to the node `inspect` method and edit options for `console.log`. A remote attacker can edit options for the `console.log` command.
12) UNIX symbolic link following (CVE-ID: CVE-2022-41973)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a symlink following issue. A local user can create a specially crafted symbolic link to a critical file on the system and overwrite it with privileges of the application.
Successful exploitation of this vulnerability may result in privilege escalation.
13) NULL pointer dereference (CVE-ID: CVE-2022-36227)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in libarchive. A remote attacker can pass a specially crafted archive to the application and perform a denial of service (DoS) attack.
14) Improper Authorization (CVE-ID: CVE-2022-31692)
The vulnerability allows a remote attacker to bypass authorization checks.
The vulnerability exists due to authorization rules bypass via forward or include dispatcher types. A remote attacker can bypass authorization process.
15) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2022-31690)
The vulnerability allows a remote attacker to escalate privileges on the system.
The vulnerability exists due to application does not properly impose security restrictions in spring-security-oauth2-client. A remote user can modify a request initiated by the Client to the Authorization Server and gain elevated privileges on the system.
16) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2022-3172)
The disclosed vulnerability allows a remote attacker to perform SSRF attacks.
The vulnerability exists due to insufficient validation of user-supplied input in kube-apiserver. A remote attacker can send a specially crafted HTTP request and trick the application to initiate requests to arbitrary systems.
Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.
17) Memory leak (CVE-ID: CVE-2022-2929)
The vulnerability allows a remote attacker to perform DoS attack on the target system.
The vulnerability exists due memory leak within the fqdn_universe_decode() function when processing DHCP packets with DNS labels. A remote attacker can send specially crafted DHCP packets to the affected server, trigger memory leak and perform denial of service attack.
18) Input validation error (CVE-ID: CVE-2022-2928)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to an error related to the way processing lease queries are processed by the DHCP server. With a DHCP server configured with "allow leasequery;" a remote attacker can send lease queries for the same lease multiple times, leading to the "add_option()" function being repeatedly called. This can cause an option's "refcount" field to overflow and the server to abort.
19) Resource management error (CVE-ID: CVE-2022-2795)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within the application when processing large delegations. A remote attacker can flood the target resolver with queries and perform a denial of service (DoS) attack.
20) Security features bypass (CVE-ID: CVE-2023-32314)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to an unexpected creation of a host object based on the specification of `Proxy`. A remote attacker can escape sandbox restrictions and gain remote code execution rights on the host.
