Description
This security bulletin contains information about 9 secuirty vulnerabilities.
1) Infinite loop (CVE-ID: CVE-2022-0778)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop within the BN_mod_sqrt() function when processing an ASN.1 certificate that contains elliptic curve public keys in compressed form or explicit elliptic curve parameters with a base point encoded in compressed form. A remote attacker can supply a specially crafted certificate to the TLS server or client, consume all available system resources and cause denial of service conditions.
2) Out-of-bounds write (CVE-ID: CVE-2022-23943)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input in mod_sed. A remote attacker can trigger out-of-bounds write and execute arbitrary code on the target system.
3) OS Command Injection (CVE-ID: CVE-2022-24828)
The vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.
The vulnerability exists due to improper input validation within the VcsDriver::getFileContent() method when parsing $file or $identifier arguments. A remote attacker can pass specially crafted data to the application and execute arbitrary OS commands on the target system, if the Mercurial or the Git driver are used.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
4) Command Injection (CVE-ID: CVE-2021-41116)
The vulnerability allows a remote attacker to execute arbitrary commands on the target system.
The vulnerability exists due to improper input validation on Windows. A remote unauthenticated attacker can pass specially crafted data to the application and execute arbitrary commands on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
5) Cross-site scripting (CVE-ID: CVE-2021-41182)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of values passed as the `altField` option of the Datepicker widget. A remote attacker can inject and execute arbitrary JavaScript 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) Cross-site scripting (CVE-ID: CVE-2021-41183)
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 when processing values of various `*Text` options. A remote attacker can pass specially crafted input to the library and execute arbitrary JavaScript 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.
7) Cross-site scripting (CVE-ID: CVE-2021-41184)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of values passed to the `of` option. A remote attacker can execute arbitrary JavaScript 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.
8) Path traversal (CVE-ID: CVE-2022-24785)
The vulnerability allows a remote attacker to perform directory traversal attacks.
The vulnerability exists due to input validation error when processing directory traversal sequences within the npm version of Moment.js. A remote attacker can send a specially crafted HTTP request and read arbitrary files on the system.
9) Input validation error (CVE-ID: CVE-2021-21707)
The vulnerability allows a remote attacker to inject arbitrary XML code.
The vulnerability exists due to insufficient validation of user-supplied input within the simplexml_load_file() PHP function when processing NULL byte character (e.g. %00). A remote attacker can pass specially crafted URL to the application and bypass implemented security restrictions.
