Vulnerability Countermeasure Information Database JVN iPedia Registration Status [2024 3rd Quarter (Jul. - Sep.)]

1. 2024 3rd Quarter: Vulnerability Countermeasure Information Database JVN iPedia Registration Status

The vulnerability countermeasure information database JVN iPedia is endeavoring to become a comprehensive vulnerability database where vulnerability information is aggregated for easy access for IT users. JVN iPedia collects and/or translates the vulnerability information published by 1) domestic software developers, 2) JVN (footnote 1), a vulnerability information portal run by JPCERT/CC and IPA, and 3) NVD (footnote 2), a vulnerability database run by NIST (footnote 3). JVN iPedia has been making vulnerability information available to the public since April 25, 2007.

1-1. Vulnerabilities Registered in 2024/3Q

JVN iPedia now stores 216,796 vulnerabilities

The summary of the vulnerability information registered to the Japanese version of JVN iPedia during the 3rd quarter (July 1 to September 30) of 2024 is shown in the table below. As of the end of September 2024, the total number of vulnerabilities stored in JVN iPedia is 216,796 (Table 1-1, Figure 1-1).

The reason for the decrease in the number of registrations on JVN iPedia in the third quarter of 2024 is not due to a delay in the release of vulnerability information on JVN iPedia during that period, but rather a delay in the release of vulnerability information on NVD.

As for the JVN iPedia English version, the total number of vulnerabilities stored is 8,763 as shown in the Table 1-2.

2-1. Types of Vulnerabilities Reported

Figure 2-1 shows the number of vulnerabilities newly added to JVN iPedia during the 3rd quarter (July 1 to September 30) of 2024, sorted by the CWE vulnerability types.

The type of the vulnerabilities reported most in the 3rd quarter is CWE-79 (Cross-Site Scripting) with 1,160 cases, followed by CWE-89 (SQL Injection) with 572, CWE-787 (Out-of-bounds Write) with 376, CWE-476 (NULL Pointer Dereference) with 225, CWE-352 (Cross-Site Request Forgery) with 209. CWE-79 (Cross-site Scripting), the most reported vulnerability type in this quarter, could allow attackers to display false webpages and/or steal information.

Software developers need to make sure to mitigate vulnerability from the planning and design phase of software development. IPA provides tools and guidelines, such as “Vulnerability Countermeasure Guide for Software Developers” (footnote 4), “How to Secure Your Web-site” (footnote 5), and “AppGoat” (footnote 6), a hands-on venerability learning tool, for website developers and operators to build secure websites.

2-2. Severity of Vulnerabilities Reported

Figure 2-2 shows the yearly change in the CVSSv2 rating scale based severity of vulnerabilities registered to JVN iPedia.

As for the vulnerabilities added to JVN iPedia in 2024, 30.2 percent are “Level 3” (7.0 - 10.0), 60.9 percent are “Level 2” (4.0 – 6.9) and 8.8 percent are “Level 1” (0.0 – 3.9). This means 91.1 percent of all vulnerabilities registered are Level 2 or higher, which are potentially critical enough to cause damage like information exposure or data falsification.

The reason for the significant decrease in the number of CVSSv2 registrations in JVN iPedia in 2024 is that CVSSv2 is not actively evaluated by NVD, the information collection source for JVN iPedia (footnote 7).

Figure 2-3 shows the yearly change in the CVSSv3 rating scale based severity of vulnerabilities registered to JVN iPedia.

As for the vulnerabilities added to JVN iPedia in 2024, 15.2 percent are “Critical” (9.0 – 10.0), 36.3 percent are “High” (7.0 – 8.9), 46.9 percent are “Medium” (4.0 – 6.9) and 1.6 percent are “Low” (0.1 – 3.9).

To avoid threats posed by the known vulnerabilities, both product developers and IT users should pay close attention to vulnerability disclosure and update software they use to a fixed version or apply a security patch as soon as possible when they become available. IT users can check vulnerabilities newly published on JVN iPedia in RSS and XML format (footnote 8) as well.

2-3. Types of Software Reported with Vulnerability

Figure 2-4 shows the yearly change in the type of software reported with vulnerability. Application vulnerabilities have been published most, accounting for 73.4 percent (16,842 out of 22,924) of the 2024 total.

Figure 2-5 shows the yearly change in the number of JVN iPedia-stored vulnerabilities in industrial control systems (ICS) used in critical infrastructure sectors. As of September 2024, the total of 6,471 ICS vulnerabilities have been registered.

2-4. Products Reported with Vulnerability

Table 2-1 lists the top 20 software whose vulnerabilities were most registered to JVN iPedia during the 3rd quarter (July 1 to September 30) of 2024. 

In this quarter, the most registered product was the Linux Kernel. After the second place, Qualcomm components and a wide range of venders' OS products were on the list, such as Google, Apple, and Microsoft.

Besides those in the top 20 list, JVN iPedia stores and offers vulnerability information about a variety of software. IPA hopes software developers and users will make good use of JVN iPedia to efficiently check vulnerability information and take necessary action in a timely manner (footnote 9).

3. Most Accessed Vulnerability Countermeasure Information

Table 3-1 lists the top 20 most accessed vulnerability countermeasure information in JVN iPedia during the 3rd quarter (July 1 to September 30) of 2024.

Many vulnerabilities in plugins for WordPress were ranked in this quarter. This is due to the mechanical access from specific organizations.
