Vulnerability Countermeasure Information Database JVN iPedia Registration Status [2020 2nd Quarter (Apr. - Jun.)]

1. 2020 2nd Quarter: Vulnerability Countermeasure Information Database JVN iPedia Registration Status

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.

1-1. Vulnerabilities Registered in 2020/2Q

~JVN iPedia now stores 120,883 vulnerabilities~

The summary of the vulnerability information registered to the Japanese version of JVN iPedia during the 2nd quarter of 2020 (April 1 to June 30, 2020) is shown in the table below. As of the end of June 2020, the total number of vulnerabilities stored in JVN iPedia is 120,883 (Table 1-1, Figure 1-1).

As for the JVN iPedia English version, the total number of vulnerabilities stored is 2,159 as shown in the lower half of the Table 1-1.

2-1. Types of Vulnerabilities Reported

Figure 2-1 shows the number of vulnerabilities newly added to JVN iPedia during the 2nd quarter of 2020, sorted by the CWE vulnerability types.  
The type of the vulnerabilities reported most in the 2nd quarter is CWE-79 (Cross-Site Scripting) with 463 cases, followed by CWE-200 (Information Exposure) with 352, CWE-20 (Improper Input Validation) with 271, CWE-269 (Improper Privilege Management) with 257, CWE-787 (Out-of-bounds Write) with 246.

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 "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.

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 2020, 23.8 percent are “Level III” (7.0 - 10.0), 61.7 percent are “Level ll” (4.0 – 6.9) and 14.5 percent are “Level I” (0.0 – 3.9). This means 85.5 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 2020, 16.0 percent are “Critical” (9.0 – 10.0), 41.5 percent are “High” (7.0 – 8.9), 40.4 percent are “Medium” (4.0 – 6.9) and 2.1 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.

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 68.4 percent (6,022 out of 8,798) of the 2020 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 2020, the total of 2,627 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 2nd quarter (April to June) of 2020.  
In this quarter, the 1st rank continued to be Microsoft Windows 10 from the previous quarter. From 2nd to 20th, other Windows OS products are also ranked. In addition, many other vulnerability information for OS products are ranked, such as Google’s mobile OS "Android", Apple's OS "iOS", etc.

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).

3. Most Accessed Vulnerability Countermeasure Information

Table 3-1 lists the top 20 most accessed vulnerability countermeasure information in JVN iPedia during the 2nd quarter of 2020 (April to June).  
In this quarter, 18 information except the 15th and 17th rank is vulnerability countermeasure information released on the Vulnerability Countermeasure Information Portal Site JVN. Information released on JVN contains information which publicized based on "Information Security Early Warning Partnership" (*9). That information attracted a lot of interest and appeared on news sites etc. so that the number of access increased.
