Vulnerability Countermeasure Information Database JVN iPedia Registration Status [2021 1st Quarter (Jan. - Mar.)]

1. 2021 1st 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 2021/1Q

~ JVN iPedia now stores 127,089 vulnerabilities ~

The summary of the vulnerability information registered to the Japanese version of JVN iPedia during the 1st quarter of 2021 (January 1 to March 31, 2021) is shown in the table below. As of the end of March 2021, the total number of vulnerabilities stored in JVN iPedia is 127,089 (Table 1-1, Figure 1-1).

As for the JVN iPedia English version, the total number of vulnerabilities stored is 2,260 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 1st quarter of 2021, sorted by the CWE vulnerability types.  
The type of the vulnerabilities reported most in the 1st quarter is CWE-79 (Cross-Site Scripting) with 170 cases, followed by CWE-269 (Improper Privilege Management) with 132 cases, CWE-20 (Improper Input Validation) with 128, CWE-787 (Out-of-bounds Write) with 64, CWE-200 (Information Exposure) with 51. 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.

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 2021, 23.5 percent are “Level III” (7.0 - 10.0), 59.5 percent are “Level ll” (4.0 – 6.9) and 17.0 percent are “Level I” (0.0 – 3.9). This means 83.0 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, 12.0 percent are “Critical” (9.0 – 10.0), 45.2 percent are “High” (7.0 – 8.9), 40.8 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 (*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 57.1 percent (972 out of 1,701) 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 March 2021, the total of 2,904 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 1st quarter (January to March) of 2021.  
In this quarter, the most registered products are Qualcomm products with 551 cases. This is due to the registration of vulnerability information for multiple Qualcomm products published from 2019 to 2020. OS products are lined up from 2nd to 16th rank, especially Microsoft's Windows products accounting for the most of them.

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).
