SB2022060315 - Multiple Vulnerabilities in IBM Netcool Agile Service Manager

Description

This security bulletin contains information about 19 secuirty vulnerabilities.

1) Input validation error (CVE-ID: CVE-2021-23840)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input during EVP_CipherUpdate, EVP_EncryptUpdate and EVP_DecryptUpdate calls. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.

2) Incorrect Regular Expression (CVE-ID: CVE-2021-27290)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to incorrect processing of SRIs. A remote attacker can pass specially crafted input to the application and perform regular expression denial of service (ReDoS) attack.

3) Out-of-bounds read (CVE-ID: CVE-2021-22918)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition in uv__idna_toascii() function in libuv, which is used to convert strings to ASCII. A remote attacker can force the application to resolve a specially crafted hostname, trigger an out-of-bounds read error and gain access to sensitive information or perform a denial of service (DoS) attack.

4) Incorrect default permissions (CVE-ID: CVE-2021-22921)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists in Windows installer due to incorrect default permissions for files and folders that are set by the application. A local user with access to the system can view contents of files and directories or modify them.

5) Incorrect Regular Expression (CVE-ID: CVE-2021-23362)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient input validation when processing regular expression "shortcutMatch" in the "fromUrl" function. A remote attacker can pass specially crafted data to the application and perform regular expression denial of service (ReDos) attack.

6) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2021-22960)

The vulnerability allows a remote attacker to preform HTTP request smuggling attacks.

The vulnerability exists due to improper validation of HTTP requests, where the application ignores chunk extensions when parsing the body of chunked requests. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.

Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.

7) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2021-22959)

The vulnerability allows a remote attacker to preform HTTP request smuggling attacks.

The vulnerability exists due to improper validation of HTTP requests, where the application accepts requests with a space right after the header name before the colon. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.

Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.

8) Resource management error (CVE-ID: CVE-2021-22883)

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 multiple connection attempts with an 'unknownProtocol'. A remote attacker can initiate multiple connections with the server, which will trigger a leak of file descriptors and result in a denial of service (DoS) condition.

9) DNS rebinding (CVE-ID: CVE-2021-22884)

The vulnerability allows a remote attacker to perform DNS rebinding attack.

The vulnerability exists due to the application whitelist includes the “localhost6” name. When “localhost6” is not present in /etc/hosts, it is treated an ordinary domain that is resolved via DNS, i.e., over network. If the attacker controls the victim's DNS server or can spoof its responses, the DNS rebinding protection can be bypassed by using the “localhost6” domain.

10) Use-after-free (CVE-ID: CVE-2021-22930)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error when processing HTTP/2 stream canceling requests. A remote attacker can send a specially crafted HTTP/2 request, trigger a use-after-free error and execute arbitrary code on the system.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.

11) Security features bypass (CVE-ID: CVE-2021-3450)

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to an error in implementation of the X509_V_FLAG_X509_STRICT flag allows an attacker to overwrite a valid CA certificate using any non-CA certificate in the chain. As a result, a remote attacker can perform MitM attack.

12) Use-after-free (CVE-ID: CVE-2020-8265)

The vulnerability allows a remote attacker to perform a DoS attack..

The vulnerability exists due to a use-after-free error in TLSWrap within the TLS implementation. A remote attacker can send specially crafted data to the service and perform a denial of service (DoS) attack.

13) HTTP request smuggling (CVE-ID: CVE-2020-8287)

The vulnerability allows a remote attacker to preform HTTP request smuggling attacks.

The vulnerability exists due to improper validation of HTTP requests. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.

Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.

14) NULL pointer dereference (CVE-ID: CVE-2020-1971)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error. A remote attacker can trigger denial of service conditions via the API functions TS_RESP_verify_response and TS_RESP_verify_token). If an attacker can control both items being compared then that attacker could trigger a crash. For example if the attacker can trick a client or server into checking a malicious certificate against a malicious CRL then this may occur. Note that some applications automatically download CRLs based on a URL embedded in a certificate. This checking happens prior to the signatures on the certificate and CRL being verified. OpenSSL's s_server, s_client and verify tools have support for the "-crl_download" option which implements automatic CRL downloading and this attack has been demonstrated to work against those tools. Note that an unrelated bug means that affected versions of OpenSSL cannot parse or construct correct encodings of EDIPARTYNAME. However it is possible to construct a malformed EDIPARTYNAME that OpenSSL's parser will accept and hence trigger this attack.

15) Prototype pollution (CVE-ID: CVE-2022-21824)

The vulnerability allows a remote attacker to perform a denial of service attack.

The vulnerability exists due to the formatting logic of the console.table() function. A remote attacker can send a specially crafted request and assign an empty string to numerical keys of the object prototype.

16) Improper Certificate Validation (CVE-ID: CVE-2021-44533)

The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to improper validation of certificate subject and issuer fields. A remote attacker can create a certificate with specially crafted multi-value Relative Distinguished Names and perform spoofing attack.

17) Improper validation of certificate with host mismatch (CVE-ID: CVE-2021-44532)

The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to improper validation of certificates, when converting SANs (Subject Alternative Names) to a string format. A remote attacker can inject special characters into the string and perform spoofing attack.

18) NULL pointer dereference (CVE-ID: CVE-2021-3449)

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 processing TLSv1.2 renegotiations. A remote attacker can send a maliciously crafted renegotiation ClientHello message, which omits the signature_algorithms extension but includes a signature_algorithms_cert extension, trigger a NULL pointer dereference error and crash the server.

19) Prototype pollution (CVE-ID: CVE-2020-7774)

The vulnerability allows a remote attacker to execute arbitrary JavaScript code.

The vulnerability exists due to improper input validation. A remote attacker can send a specially crafted request and execute arbitrary JavaScript code.
