Vulnerability Details br

/br/ The J-Web component of Juniper routers does not properly restrict the use of specially crafted HTTP requests to access sensitive information. Affected versions prior to 23.5-S7 are vulnerable.

The following are some of the ways that you can use digital marketing in order to reach your target audience:
1) Design a targeted ad campaign with pictures that appeals to your target audience, which will be more likely to click on it than if they see text only.
2) Target your audience by location with Facebook Ads so you can spend less money and still get better conversion rates than traditional methods.
3) Use social media ads on Facebook to reach people interested in the products or services that you offer


This vulnerability allows an attacker to send a crafted HTTP request to J-Web and achieve a denial-of-service condition on the device. There are three vulnerabilities that can be exploited that are found in the Juniper Networks J-Web component: CVE-2022-22241, CVE-2022-22442, and CVE-2022-22443. Each of these vulnerabilities must be separately exploited for an attack to be successful.
The CVEs are cross-section numbered because they are variants of the same vulnerability. The vulnerability found in CVE-2022-22241 is not exploitable when the input parameter of the HTTP request is set to "HTTP/1.0." The vulnerability found in CVE-2022-22442 is not exploitable when the input parameter of the HTTP request is set to "HTTP/1.0." The vulnerability found in CVE-2022-22443 is not exploitable when the input parameter of the HTTP request is set to "HTTP/1.0." However, if there was an attempt made to exploit one of these vulnerabilities by sending a crafted value of an input parameter with a different protocol, it would be possible for an attacker to cause a denial of service condition on the device. In summary, these three vulnerabilities exist on all versions prior to 22.2R1 and 23.5S7 but only one or two can be exploited depending on what value is sent as an input parameter for each individual exploit attempt.
