CVE-2023-7101 (GCVE-0-2023-7101)

Vulnerability from cvelistv5 – Published: 2023-12-24 21:34 – Updated: 2025-10-21 23:05
VLAI
Title
Arbitrary Code Execution (ACE) Vulnerability
Summary
Spreadsheet::ParseExcel version 0.65 is a Perl module used for parsing Excel files. Spreadsheet::ParseExcel is vulnerable to an arbitrary code execution (ACE) vulnerability due to passing unvalidated input from a file into a string-type “eval”. Specifically, the issue stems from the evaluation of Number format strings (not to be confused with printf-style format strings) within the Excel parsing logic.

Title
Authenticated eval injection in B. Braun Space Battery pack SP with Wi-Fi
Summary
An improper neutralization of directives in dynamically evaluated code vulnerability in the WiFi Battery embedded web server in versions L90/U70 and L92/U92 can be used to gain administrative access to the WiFi communication module. An authenticated user, having access to both the medical device WiFi network (such as a biomedical engineering staff member) and the specific B.Braun Battery Pack SP with WiFi web server credentials, could get administrative (root) access on the infusion pump communication module. This could be used as a vector to start further attacks

CVE-2022-41931 (GCVE-0-2022-41931)

Vulnerability from cvelistv5 – Published: 2022-11-23 00:00 – Updated: 2025-04-22 16:01

Title
Improper Neutralization of Directives in Dynamically Evaluated Code ('Eval Injection') in xwiki-platform-icon-ui
Summary
xwiki-platform-icon-ui is vulnerable to Improper Neutralization of Directives in Dynamically Evaluated Code ('Eval Injection'). Any user with view rights on commonly accessible documents including the icon picker macro can execute arbitrary Groovy, Python or Velocity code in XWiki due to improper neutralization of the macro parameters of the icon picker macro. The problem has been patched in XWiki 13.10.7, 14.5 and 14.4.2. Workarounds: The [patch](https://github.com/xwiki/xwiki-platform/commit/47eb8a5fba550f477944eb6da8ca91b87eaf1d01) can be manually applied by editing `IconThemesCode.IconPickerMacro` in the object editor. The whole document can also be replaced by the current version by importing the document from the XAR archive of a fixed version as the only changes to the document have been security fixes and small formatting changes.

CVE-2022-36100 (GCVE-0-2022-36100)

Vulnerability from cvelistv5 – Published: 2022-09-08 21:10 – Updated: 2025-04-22 17:22
VLAI
Title
XWiki Platform Applications Tag and XWiki Platform Tag UI vulnerable to Eval Injection
Summary
XWiki Platform Applications Tag and XWiki Platform Tag UI are tag applications for XWiki, a generic wiki platform. Starting with version 1.7 in XWiki Platform Applications Tag and prior to 13.10.6 and 14.4 in XWiki Platform Tag UI, the tags document `Main.Tags` in XWiki didn't sanitize user inputs properly. This allowed users with view rights on the document (default in a public wiki or for authenticated users on private wikis) to execute arbitrary Groovy, Python and Velocity code with programming rights. This also allowed bypassing all rights checks and thus both modification and disclosure of all content stored in the XWiki installation. The vulnerability could be used to impact the availability of the wiki. On XWiki versions before 13.10.4 and 14.2, this can be combined with CVE-2022-36092, meaning that no rights are required to perform the attack. The vulnerability has been patched in versions 13.10.6 and 14.4. As a workaround, the patch that fixes the issue can be manually applied to the document `Main.Tags` or the updated version of that document can be imported from version 14.4 of xwiki-platform-tag-ui using the import feature in the administration UI on XWiki 10.9 and later.

Mitigation
Architecture and Design Implementation

Strategy: Refactoring

If possible, refactor your code so that it does not need to use eval() at all.

Mitigation MIT-5
Implementation

Strategy: Input Validation

  • Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
  • When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
  • Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
Mitigation
Implementation
  • Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180, CWE-181). Make sure that your application does not inadvertently decode the same input twice (CWE-174). Such errors could be used to bypass allowlist schemes by introducing dangerous inputs after they have been checked. Use libraries such as the OWASP ESAPI Canonicalization control.
  • Consider performing repeated canonicalization until your input does not change any more. This will avoid double-decoding and similar scenarios, but it might inadvertently modify inputs that are allowed to contain properly-encoded dangerous content.
Mitigation
Implementation

For Python programs, it is frequently encouraged to use the ast.literal_eval() function instead of eval, since it is intentionally designed to avoid executing code. However, an adversary could still cause excessive memory or stack consumption via deeply nested structures [REF-1372], so the python documentation discourages use of ast.literal_eval() on untrusted data [REF-1373].

CAPEC-35: Leverage Executable Code in Non-Executable Files

An attack of this type exploits a system's trust in configuration and resource files. When the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high.
