#vulnerability

### Description Leantime allows stored cross-site scripting (XSS) in the API key name while generating the API key. ### Impact Any low privileged user like manager, or editor, can create an API key with XSS payload. When admin will visit the Company page, the XSS will automatically get triggerred leading to the unauthorized action performed from the ADMIN account. Like, removing any user, or adding someone else as high privilege, and many more.

**CSRF** ### Summary A cross-site request forgery vulnerability allows a remote actor to create an account with Owner privileges. By luring an Owner or Administrator into clicking a button on an attacker-controlled website, a request will be issued, generating an account with the attacker's information and role of their choosing. ### Impact While the likelihood of a successful exploit is low, the impact would be high as the attacker could then gain complete control over the victim's environment.

### Summary A cross-site scripting (XSS) vulnerability has been identified in Leantime. The vulnerability allows an attacker to inject malicious scripts into certain fields, potentially leading to the execution of arbitrary code or unauthorized access to user-sensitive information. The code does not include any validation or sanitization of the $_GET["id"] parameter. As a result, it directly incorporates the user-supplied value into the source path without any checks.

Multiple evaluation of a single expression is possible in the iterator target of a for loop. While the iterator expression cannot produce multiple writes, it can consume side effects produced in the loop body (e.g. read a storage variable updated in the loop body) and thus lead to unexpected program behavior. Specifically, reads in iterators which contain an ifexp (e.g. `for s: uint256 in ([read(), read()] if True else [])`) may interleave reads with writes in the loop body. The fix is tracked in https://github.com/vyperlang/vyper/pull/4488. ### Vulnerability Details Vyper for loops allow two kinds of iterator targets, namely the `range()` builtin and an iterable type, like SArray and DArray. During codegen, iterable lists are required to not produce any side-effects (in the following code, `range_scope` forces `iter_list` to be parsed in a constant context, which is checked against `is_constant`). ```python def _parse_For_list(self): with self.context.range_scope(): ...

Vyper's `sqrt()` builtin uses the babylonian method to calculate square roots of decimals. Unfortunately, improper handling of the oscillating final states may lead to sqrt incorrectly returning rounded up results. the fix is tracked in https://github.com/vyperlang/vyper/pull/4486 ### Vulnerability Details Vyper injects the following code to handle calculation of decimal sqrt. x is the input provided by user. ```python assert x >= 0.0 z: decimal = 0.0 if x == 0.0: z = 0.0 else: z = x / 2.0 + 0.5 y: decimal = x for i: uint256 in range(256): if z == y: break y = z z = (x / z + z) / 2.0 ``` Notably, the terminal condition of the algorithm is either `z_cur == z_prev`, or the algorithm runs for 256 rounds. However, for certain inputs, `z` might actually oscillate between `N` and `N + epsilon`, where `N ** 2 <= x < (N + epsilon) ** 2`. This means that the current behavior does not define whether it will round up or down to the nearest...

### Summary Stored XSS, also known as persistent XSS, is the more damaging of the two. It occurs when a malicious script is injected directly into a vulnerable web application. ### Details A Stored Cross-Site Scripting (XSS) vulnerability was found that could potentially compromise user data and pose a significant security risk to the platform. ### PoC - Create a project - Navigate to project - Visit to the integration - Add malicious payload inside the webhook and save it. - Notice the alert dialogue indicating successful execution of the XSS payload. ``` '';!--" onfocus=alert(0) autofocus="" onload=alert(3);="&amp;{(alert(1))}" |="" mufazmi"=" ``` ``` '';!--" onfocus=alert(0) autofocus="" onload=alert(3);=>>"&amp;{(alert(1))}" |="">> mufazmi"=">> ``` ### POC https://youtu.be/kqKFgsOqstg ### Impact This XSS vulnerability allows an attacker to execute malicious scripts in the context of a victim's browser when they click on a specially crafted link. This could lead to various m...

### Summary The vulnerability in Leantime's "overdue" section allows attackers to upload malicious image files containing XSS payloads. When other users view these files, the scripts execute, enabling attackers to steal sensitive information or perform unauthorized actions. Improving input validation and output encoding in the file upload process can prevent this exploit. Accessing and enhancing the relevant source code modules is crucial for addressing this security flaw effectively. ### Impact This XSS vulnerability allows attackers to inject malicious scripts into the Leantime application, compromising user data, session tokens, and potentially executing unauthorized actions on behalf of users. Exploitation could lead to account takeover, data theft, and unauthorized access to sensitive information, posing a significant risk to user privacy, data integrity, and system security.

Due to improper cache control an attacker can view sensitive information even if they are not logged into the account anymore. Additional Information: 1.The issue was identified during routine security testing. 2.This vulnerability poses a significant risk to user privacy and data security. 3.Urgent action is recommended to mitigate this vulnerability and protect user data from unauthorized access.
