Enhancing information security
Release Date:Aug 25, 2021
IT Security Center
The vulnerability countermeasure information database JVN iPedia (https://jvndb.jvn.jp/en/) 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 (*1), a vulnerability information portal run by JPCERT/CC and IPA, and 3) NVD (*2), a vulnerability database run by NIST (*3). JVN iPedia has been making vulnerability information available to the public since April 25, 2007.
~ JVN iPedia now stores 129,824 vulnerabilities ~
The summary of the vulnerability information registered to the Japanese version of JVN iPedia during the 2nd quarter of 2021 (April 1 to June 30, 2021) is shown in the table below. As of the end of June 2021, the total number of vulnerabilities stored in JVN iPedia is 129,824 (Table 1-1, Figure 1-1).
As for the JVN iPedia English version, the total number of vulnerabilities stored is 2,301 as shown in the lower half of the Table 1-1.

Figure 2-1 shows the number of vulnerabilities newly added to JVN iPedia during the 2nd quarter of 2021, sorted by the CWE vulnerability types.
The type of the vulnerabilities reported most in the 2nd quarter is CWE-79 (Cross-Site Scripting) with 264 cases, followed by CWE-20 (Improper Input Validation) with 134, CWE-269 (Improper Privilege Management) with 101 cases, CWE-787 (Out-of-bounds Write) with 88, CWE-200 (Information Exposure) with 87. 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"" (*4), "How to Secure Your Website" (*5), "Secure Programming Guide" (*6) and "AppGoat" (*7), a hands-on venerability learning tool, for website developers and operators to build secure websites.
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 2021, 22.0 percent are “Level III” (7.0 - 10.0), 62.9 percent are “Level ll” (4.0 – 6.9) and 15.1 percent are “Level I” (0.0 – 3.9). This means 84.9 percent of all vulnerabilities registered are Level II or higher, which are potentially critical enough to cause damage like information exposure or data falsification.
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 2021, 12.8 percent are “Critical” (9.0 – 10.0), 45.2 percent are “High” (7.0 – 8.9), 39.4 percent are “Medium” (4.0 – 6.9) and 2.6 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 (*8) as well.
Figure 2-4 shows the yearly change in the type of software reported with vulnerability. Application vulnerabilities have been published most, accounting for 68.4 percent (3,034 out of 4,436) of the 2021 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 June 2021, the total of 2,959 ICS vulnerabilities have been registered.
Table 2-1 lists the top 20 software whose vulnerabilities were most registered to JVN iPedia during the 2nd quarter (April to June) of 2021.
In this quarter, the most registered products were Qualcomm products which continued from previous quarter, with 460 cases. This is due to the registration of vulnerability information for multiple Qualcomm products which published in 2020. In addition, OS products, such as Microsoft Windows Products, account for 14 of the top 20.
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 (*9).

Table 3-1 lists the top 20 most accessed vulnerability countermeasure information in JVN iPedia during the 2nd quarter of 2021 (April to June).
In this quarter, the most accessed vulnerability countermeasure information was "phpMyAdmin vulnerable to cross-site scripting" published in 2014. This is because there was a lot of access which was considered mechanical from specific organizations. In addition, vulnerability countermeasure information published on the vulnerability countermeasure information portal site JVN accounted for 17 of the top 20.
