Welcart e-Commerce < 2.2.8 - Missing Capabilities Check to Information Disclosure

Noroxi assessment

Priority: Monitor (action score 21/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.80% (FIRST EPSS); higher than 56% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: uscnanbu Welcart e-Commerce 2.2.8.
  • Severity is disputed: the assigning authority (CNA) scores it 7.5, NVD 5.3.

Low priority for now. Upgrade to uscnanbu Welcart e-Commerce 2.2.8 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

The Welcart e-Commerce plugin for WordPress is vulnerable to authorization bypass due to missing capability checks on the download_orderdetail_list(), change_orderlist(), and download_member_list() functions called via admin_init hooks in versions up to, and including, 2.2.7. This makes it possible for unauthenticated attackers to download lists of members, products and orders.
