CVE-2022-34770: Tabit - sensitive information disclosure. Several APIs on the web system display, without authorization, sensitive information such as health statements, previous bills in a specific restaurant, alcohol consumption and smoking habits. Each of the described API’s, has in its URL one or more MongoDB ID which is not so simple to enumerate. However, they each receive a ‘tiny URL’ in Tabit’s domain, in the form of https://tbit.be/{suffix} with suffix being a 5 characters long string containing numbers, lower- and upper-case letters. It is not so simple to enumerate them all, but really easy to find some that work and lead to a personal endpoint. This is both an example of OWASP: API4 - rate limiting and OWASP: API1 - Broken object level authorization. Furthermore, the redirect URL disclosed the MongoDB IDs discussed above, and we could use them to query other endpoints disclosing more personal information. For example: The URL https://tabitisrael.co.il/online-reservations/health-statement?orgId={org_id}&healthStatementId={health_statement_id} is used to invite friends to fill a health statement before attending the restaurant. We can use the health_statement_id to access the https://tgm-api.tabit.cloud/health-statement/{health_statement_id} API which disclose medical information as well as id number.
The exploitability of CVE-2022-34770 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
This vulnerability, CVE-2022-34770, requires a high level of attack complexity and low privileges, making it difficult but not impossible to exploit. Organizations should ensure robust security configurations to mitigate risks.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2022-34770, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2022-34770, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
The EPSS score estimates the probability that this vulnerability will be exploited in the near future.
EPSS Score: 0.126% (probability of exploit)
EPSS Percentile: 48.78%
(lower percentile = lower relative risk)
This vulnerability is less risky than approximately 51.22% of others.
