Vulnerability Countermeasure Information Database JVN iPedia Registration Status [2021 3rd Quarter (Jul. - Sep.)]

1. 2021 3rd 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 2021/3Q

~ JVN iPedia now stores 133,026 vulnerabilities ~ The summary of the vulnerability information registered to the Japanese version of JVN iPedia during the 3rd quarter of 2021 (July 1 to September 30, 2021) is shown in the table below. As of the end of September 2021, the total number of vulnerabilities stored in JVN iPedia is 133,026 (Table 1-1, Figure 1-1). As for the JVN iPedia English version, the total number of vulnerabilities stored is 2,337 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 3rd quarter of 2021, sorted by the CWE vulnerability types.

The type of the vulnerabilities reported most in the 3rd quarter is CWE-79 (Cross-Site Scripting) with 364 cases, followed by CWE-787 (Out-of-bounds Write) with 217, CWE-269 (Improper Privilege Management) with 161, CWE-416 (Use After Free) with 92, CWE-125 (Out-of-bounds Read) with 91. CWE-79 (Cross-Site Scripting), the most reported vulnerability type in this quarter, could allow at-tackers 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, 22.1 percent are “Level III” (7.0 - 10.0), 62.0 percent are “Level ll” (4.0 – 6.9) and 15.9 percent are “Level I” (0.0 – 3.9). This means 84.1 percent of all vulnerabilities registered are Level II or higher, which are potentially critical enough to cause damage like information exposure or data falsification.

• 

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 70.6 percent (5,395 out of 7,638) 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 September 2021, the total of 3,043 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 to September) of 2021.

In this quarter, the most registered product was Microsoft Windows Server 2019 with 160 cases. Many other Microsoft Windows products were also registered, accounting for 9 of the top 20, or about half.

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).

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 of 2021 (July to September). In this quarter, vulnerability countermeasure information of WordPress released in July 2020 took the 1st through 4th rank. This was due to the large number of access from specific organizations that considered to be mechanical. In addition, vulnerability countermeasure information published on the vulnerability countermeasure information portal site JVN accounted for 15 of the top 20.
