Description
This security bulletin contains information about 17 secuirty vulnerabilities.
1) Key management errors (CVE-ID: CVE-2018-9234)
The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.The weakness exists due to missing enforcement of a configuration in which key certification requires an offline master Certify key, which results in apparently valid certifications that occurred only with access to a signing subkey. A remote attacker can gain access to potentially sensitive information.
2) Cryptographic issues (CVE-ID: CVE-2023-20900)
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to improper verification of SAML token signature. A remote attacker can bypass SAML token signature verification and perform man-in-the-middle (MITM) network positioning between vCenter server and the virtual machine.
3) Use-after-free (CVE-ID: CVE-2023-4733)
The vulnerability allows a remote attacker to crash the application.
The vulnerability exists due to a use-after-free error within the do_ecmd() function in ex_cmds.c. A remote attacker can trick the victim to open a specially crafted file and crash the application.
4) Cleartext transmission of sensitive information (CVE-ID: CVE-2023-40217)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to an error in ssl.SSLSocket implementation when handling TLS client authentication. A remote attacker can trick the application to send data unencrypted.
5) Incorrect default permissions (CVE-ID: CVE-2022-41946)
The vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to application stores files with sensitive information in system's temporary directory. A local user can read the files and gain access to sensitive information.
6) Buffer overflow (CVE-ID: CVE-2023-28736)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error. A local user can trigger memory corruption and execute arbitrary code with elevated privileges.
7) Memory leak (CVE-ID: CVE-2023-35945)
The vulnerability allows a remote attacker to perform DoS attack on the target system.
The vulnerability exists due memory leak when handling HTTP/2 requests within the nghttp2 codec. A remote attacker can send RST_STREAM immediately followed by the GOAWAY frames to the application and force memory leak.
8) Integer overflow (CVE-ID: CVE-2022-36402)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to integer overflow in drivers/gpu/vmxgfx/vmxgfx_execbuf.c. A local user can trigger an integer overflow and crash the kernel.
9) Resource exhaustion (CVE-ID: CVE-2023-38039)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not limit the size of received headers from a single request that are stored for future reference. A remote attacker can send overly large HTTP responses to the application and consume all memory resources.
10) Resource exhaustion (CVE-ID: CVE-2021-42340)
The vulnerability allows a remote attacker to perform DoS attack on the target system.The vulnerability exists due memory leak when processing HTTP connections. A remote attacker can initiate multiple HTTP connections with the web server and consume all available memory on the system.
11) External control of file name or path (CVE-ID: CVE-2023-38546)
The vulnerability allows an attacker to inject arbitrary cookies into request.
The vulnerability exists due to the way cookies are handled by libcurl. If a transfer has cookies enabled when the handle is duplicated, the
cookie-enable state is also cloned - but without cloning the actual
cookies. If the source handle did not read any cookies from a specific
file on disk, the cloned version of the handle would instead store the
file name as none (using the four ASCII letters, no quotes).
none - if such a file exists and is readable in the current directory of the program using libcurl. 12) Heap-based buffer overflow (CVE-ID: CVE-2023-38545)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the SOCKS5 proxy handshake. A remote attacker can trick the victim to visit a malicious website, trigger a heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system but requires that SOCKS5 proxy is used and that SOCKS5 handshake is slow (e.g. under heavy load or DoS attack).
13) Resource exhaustion (CVE-ID: CVE-2023-3341)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources when handling control channel messages . A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
14) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2022-44729)
The disclosed vulnerability allows a remote attacker to perform SSRF attacks.
The vulnerability exists due to insufficient validation of user-supplied input. 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.
15) Out-of-bounds read (CVE-ID: CVE-2023-31122)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition within mod_macro module. A remote attacker can send specially crafted requests to the server, trigger an out-of-bounds read error and perform a denial of service (DoS) attack.
16) Open redirect (CVE-ID: CVE-2023-41080)
The vulnerability allows a remote attacker to redirect victims to arbitrary URL.
The vulnerability exists due to improper sanitization of user-supplied data, if the ROOT (default) web application is configured to use FORM authentication. A remote attacker can create a link that leads to a trusted website, however, when clicked, redirects the victim to arbitrary domain.
Successful exploitation of this vulnerability may allow a remote attacker to perform a phishing attack and steal potentially sensitive information.
17) Data Handling (CVE-ID: CVE-2022-29885)
The vulnerability allows a remote attacker to perform DoS attack.
The vulnerability exists due to an error in documentation for the EncryptInterceptor, which incorrectly stated that it enabled Tomcat clustering to run over an untrusted network. A remote attacker can perform a denial of service attack against the exposed EncryptInterceptor.
