Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) Improper Neutralization of Argument Delimiters in a Command (CVE-ID: CVE-2022-21235)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to argument strings being passed to hg in a way that additional flags can be set when hg is executed. A remote attacker can send a specially crafted request and execute arbitrary code on the target system.
2) Buffer overflow (CVE-ID: CVE-2020-24736)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error when executing a crafted SELECT query. A local user can execute a specially crafted query to trigger memory corruption and perform a denial of service (DoS) attack.
3) 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.
4) 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.
5) Input validation error (CVE-ID: CVE-2023-1667)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to multiple errors in kex implementation, related to kex guessing algorithm. A remote attacker can bypass implemented security restrictions.
6) Improper Authentication (CVE-ID: CVE-2023-2283)
The vulnerability allows a remote attacker to bypass authentication process.
The vulnerability exists due to an error within the pki_verify_data_signature() function in pki_crypto.c. The pki_key_check_hash_compatible() function can return SSH_OK value if memory allocation error happens later in the function. The A remote attacker can bypass authentication process and gain unauthorized access to the system.
7) Memory leak (CVE-ID: CVE-2023-2602)
The vulnerability allows a remote attacker to perform DoS attack on the target system.
The vulnerability exists due memory leak in the error handling in the __wrap_pthread_create() function. A remote attacker can send a specially crafted request, exploit vulnerability to exhaust the process memory and cause a denial of service condition.
8) PHP file inclusion (CVE-ID: CVE-2023-2603)
The vulnerability allows a remote attacker to include and execute arbitrary PHP files on the server.
The vulnerability exists due to incorrect input validation when including PHP files in web/ajax/modal.php. A remote non-authenticated attacker can send a specially crafted HTTP request to the affected application, include and execute arbitrary PHP code on the system with privileges of the web server.
9) State Issues (CVE-ID: CVE-2023-27536)
The vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to cURL will reuse a previously created connection even when the GSS delegation (CURLOPT_GSSAPI_DELEGATION) option had been changed that could have changed the user's permissions in a second transfer. libcurl keeps previously used connections in a connection pool for subsequent transfers to reuse if one of them matches the setup. However, this GSS delegation setting was left out from the configuration match checks, making them match too easily, affecting krb5/kerberos/negotiate/GSSAPI transfers.
10) Improper certificate validation (CVE-ID: CVE-2023-28321)
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to improper certificate validation when matching wildcards in TLS certificates for IDN names. A remote attacker crate a specially crafted certificate that will be considered trusted by the library.
Successful exploitation of the vulnerability requires that curl is built to use OpenSSL, Schannel or Gskit.
11) NULL pointer dereference (CVE-ID: CVE-2023-28484)
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 xmlSchemaFixupComplexType. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
12) Resource management error (CVE-ID: CVE-2023-29469)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources when working with hashes of empty dict strings. A remote attacker can and perform a denial of service (DoS) attack.
