Analysis Summary
CVE-2021-23820
Node.js json-pointer module could allow a remote attacker to execute arbitrary code on the system, caused by a prototype pollution flaw in the pointer components. By adding or modifying properties of Object.prototype using a __proto__ or constructor payload, an attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service condition on the system.
CVE-2021-23807
Node.js jsonpointer module could allow a remote attacker to execute arbitrary code on the system, caused by a prototype pollution flaw in the pointer components. By adding or modifying properties of Object.prototype using a __proto__ or constructor payload, an attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service condition on the system.
CVE-2021-23784
Node.js tempura module is vulnerable to cross-site scripting, caused by improper validation of user-supplied input by the esc function. A remote attacker could exploit this vulnerability to inject malicious script into a Web page which would be executed in a victim’s Web browser within the security context of the hosting Web site, once the page is viewed. An attacker could use this vulnerability to steal the victim’s cookie-based authentication credentials.
CVE-2021-23624
Node.js dotty module could allow a remote attacker to execute arbitrary code on the system, caused by a prototype pollution flaw in the path parameter. By adding or modifying properties of Object.prototype using a __proto__ or constructor payload, an attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service condition on the system.
CVE-2021-23509
Node.js json-ptr module could allow a remote attacker to execute arbitrary code on the system, caused by a prototype pollution flaw in the pointer parameter. By adding or modifying properties of Object.prototype using a __proto__ or constructor payload, an attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service condition on the system.
CVE-2021-23472
Node.js bootstrap-table module is vulnerable to cross-site scripting, caused by improper validation of user-supplied input. A remote attacker could exploit this vulnerability to inject malicious script into a Web page which would be executed in a victim’s Web browser within the security context of the hosting Web site, once the page is viewed. An attacker could use this vulnerability to steal the victim’s cookie-based authentication credentials.
