Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) Cross-site scripting (CVE-ID: N/A)
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 API Manager UI. A remote attacker can trick the victim to follow a specially crafted link 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.
2) Improper control of interaction frequency (CVE-ID: N/A)
The vulnerability allows a remote attacker to perform DoS attack.
The vulnerability exists due to missing limitations on the number of requests sent to the "/register" endpoint of API Manager. A remote attacker can create numerous registrations and perform a denial of service (DoS) attack.
3) Security features bypass (CVE-ID: N/A)
The vulnerability allows a remote user to bypass implemented security restrictions.
The vulnerability exists due to password policy is not applied at the backend. A remote user can bypass UI restrictions and set weak password for their account.
4) Cross-site scripting (CVE-ID: CVE-2019-16728)
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. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code through Mutation XSS 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.
Note: This vulnerability exists because of innerHTML mutation XSS (mXSS) for an SVG element or a MATH element.
5) Type Confusion (CVE-ID: CVE-2023-0286)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a type confusion error related to X.400 address processing inside an X.509 GeneralName. A remote attacker can pass specially crafted data to the application, trigger a type confusion error and perform a denial of service (DoS) attack or read memory contents.
In most cases, the attack requires the attacker to provide both the certificate chain and CRL, neither of which need to have a valid signature. If the attacker only controls one of these inputs, the other input must already contain an X.400 address as a CRL distribution point, which is uncommon. As such, this vulnerability is most likely to only affect applications which have implemented their own functionality for retrieving CRLs over a network.
6) Information Exposure Through Timing Discrepancy (CVE-ID: CVE-2022-4304)
The vulnerability allows a remote attacker to obtain sensitive information.
The vulnerability exists due to a timing based side channel exists in the OpenSSL RSA Decryption implementation. A remote attacker can perform a Bleichenbacher style attack and decrypt data sent over the network.
To achieve a successful decryption an attacker would have to be able to send a very large number of trial messages for decryption. The vulnerability affects all RSA padding modes: PKCS#1 v1.5, RSA-OEAP and RSASVE.
7) Out-of-bounds read (CVE-ID: CVE-2022-4203)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition when performing name constraint checking of the X.509 certificates. A remote attacker can pass a specially crafted X.509 certificate to the affected server, trigger an out-of-bounds read error and read contents of memory on the system.
8) Use-after-free (CVE-ID: CVE-2023-0215)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error within the BIO_new_NDEF function. A remote attacker can trigger a use-after-free error and perform a denial of service (DoS) attack.
9) Double Free (CVE-ID: CVE-2022-4450)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error within the PEM_read_bio_ex() function. A remote attacker can pass specially crafted PEM file to the application, trigger a double free error and perform a denial of service (DoS) attack.
10) Release of invalid pointer or reference (CVE-ID: CVE-2023-0216)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to invalid pointer dereference in d2i_PKCS7 functions. A remote attacker can perform a denial of service (DoS) attack.
11) NULL pointer dereference (CVE-ID: CVE-2023-0217)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error when validating the DSA public key. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
12) NULL pointer dereference (CVE-ID: CVE-2023-0401)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error during PKCS7 data verification. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
