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 102,651 vulnerabilities ~
The summary of the vulnerability information registered to the Japanese version of JVN iPedia during the 2nd quarter of 2019 (April 1 to June 30, 2019) is shown in the table below. As of the end of June 2019, the total number of vulnerabilities stored in JVN iPedia is 102,651 (Table 1-1, Figure 1-1).
As for the JVN iPedia English version, the total number of vulnerabilities stored is 2,048 as shown in the lower half of the Table 1-1.
| Information Source | Registered Cases | Cumulative Cases | |
|---|---|---|---|
| Japanese Version | Domestic Product Developers | 5 cases | 218 cases |
| JVN | 325 cases | 8,672 cases | |
| NVD | 4,877 cases | 93,761 cases | |
| Total | 5,207 cases | 102,651 cases | |
| English Version | Domestic Product Developers | 4 cases | 217 cases |
| JVN | 25 cases | 1,831 cases | |
| Total | 29 cases | 2,048 cases |
Figure 2-1 shows the number of vulnerabilities newly added to JVN iPedia during the 2nd quarter of 2019, sorted by the CWE vulnerability types.
The type of the vulnerabilities reported most in the 2nd quarter is CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer (Buffer Errors)) with 579 cases, followed by CWE-79 (Cross-Site Scripting) with 561, CWE-20 (Improper Input Validation) with 518, CWE-200 (Information Exposure) with 378, CWE-264 (Permissions, Privileges, and Access Controls) with 306.
CWE-119 (buffer error), the most reported vulnerability type in this quarter, could allow attackers to execute malicious code on the target server or PC, resulting in damage such as data interception or falsification.
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 "How to Secure Your Website" (*4), "Secure Programing Guide" (*5) and "AppGoat" (*6), 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 2019, 27.4 percent are “Level III” (7.0 - 10.0), 61.9 percent are “Level ll” (4.0 – 6.9) and 10.7 percent are “Level I” (0.0 – 3.9). This means 89.3 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 2019, 16.0 percent are “Critical” (9.0 – 10.0), 44.0 percent are “High” (7.0 – 8.9), 39.1 percent are “Medium” (4.0 – 6.9) and 0.9 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 (*7) 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 74.6 percent (7,445 out of 9,977) of the 2019 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 2019, the total of 1,969 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 2019.
In this quarter, large number of vulnerability countermeasure information related to OS products have been registered and which accounts for over 70% of the total. Of the top 20 cases, 9 are Microsoft OS, 4 are Apple OS, and 2 are Linux-based OS.
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 (*8).

Table 3-1 lists the top 20 most accessed vulnerability information in JVN iPedia during the 2nd quarter of 2019 (April to June).
Of the vulnerability countermeasure information ranked high in this quarter, the 3rd and 19th rank were collected from domestic product developers. Except for the above two and the 4th rank, 17 are vulnerability countermeasure information released on the Vulnerability Countermeasure Information Portal Site JVN. Those products registered in the vulnerability countermeasure information have many domestic users and receive a lot of attention so that the number of access the relevant web site tend to increase.
