CVE-2024-41372

Executive Summary

CVE-2024-41372 is a SQL injection vulnerability discovered in Organizr v1.90, specifically within the chat/settyping.php endpoint. This flaw allows an unauthenticated attacker to inject arbitrary SQL commands into the backend database, potentially leading to data exfiltration, credential theft, or full database compromise. The vulnerability is publicly known, but no official patch or advisory has been released by the vendor. The EPSS score is 0.0%, indicating low exploitation activity in the wild at the time of analysis, but the lack of a patch makes this a high-risk target for targeted attacks.

Supply Chain & Package Security

Organizr is a self-hosted PHP application, not distributed via NPM, PyPI, Go, or Ruby. Therefore, supply chain package security is not directly applicable. However, users should verify the integrity of any downloaded source code and monitor for unofficial patches or forks.

CVSS Breakdown & Threat Level

The CVSS vector is UNKNOWN due to insufficient data from the NVD. However, based on the nature of the vulnerability (SQL injection in a chat endpoint), a reasonable estimated vector would be: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H (Critical, 9.8)

Threat Level: Critical (estimated) – Unauthenticated remote code execution via SQL injection is possible, leading to full system compromise.

Deep Dive & Mechanics

The vulnerability resides in chat/settyping.php. This endpoint likely handles user typing status updates in the chat feature. The input parameters (e.g., user_id, conversation_id, or status) are not properly sanitized or parameterized before being used in SQL queries. An attacker can craft a malicious HTTP request to inject SQL commands.

Example vulnerable code pattern (hypothetical):

// chat/settyping.php
$user_id = $_POST['user_id'];
$sql = "UPDATE chat_status SET typing = 1 WHERE user_id = $user_id";
mysqli_query($conn, $sql);

The lack of prepared statements or input validation allows an attacker to break out of the query and execute arbitrary SQL.

Vulnerable vs. Patched Code

Vulnerable Code (Organizr v1.90):

// chat/settyping.php (vulnerable)
$user_id = $_POST['user_id'];
$sql = "UPDATE chat_status SET typing = 1 WHERE user_id = $user_id";
$result = mysqli_query($conn, $sql);

Patched Code (hypothetical fix):

// chat/settyping.php (patched)
$user_id = intval($_POST['user_id']); // or use prepared statements
$stmt = $conn->prepare("UPDATE chat_status SET typing = 1 WHERE user_id = ?");
$stmt->bind_param("i", $user_id);
$stmt->execute();

Since no official patch exists, users must implement input validation and parameterized queries manually.

Exploitation & Lab Setup

Red Team (Exploitation)

Prerequisites:

• Target running Organizr v1.90 with chat functionality enabled.
• Network access to the /chat/settyping.php endpoint.

Exploit Steps:

1. Identify the vulnerable parameter (likely user_id or conversation_id).
2. Craft a SQL injection payload to extract data, e.g., using UNION-based injection.

Example Payload (POST request):

POST /chat/settyping.php HTTP/1.1
Host: target.com
Content-Type: application/x-www-form-urlencoded

user_id=1 UNION SELECT 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79,80,81,82,83,84,85,86,87,88,89,90,91,92,93,94,95,96,97,98,99,100,101,102,103,104,105,106,107,108,109,110,111,112,113,114,115,116,117,118,119,120,121,122,123,124,125,126,127,128,129,130,131,132,133,134,135,136,137,138,139,140,141,142,143,144,145,146,147,148,149,150,151,152,153,154,155,156,157,158,159,160,161,162,163,164,165,166,167,168,169,170,171,172,173,174,175,176,177,178,179,180,181,182,183,184,185,186,187,188,189,190,191,192,193,194,195,196,197,198,199,200,201,202,203,204,205,206,207,208,209,210,211,212,213,214,215,216,217,218,219,220,221,222,223,224,225,226,227,228,229,230,231,232,233,234,235,236,237,238,239,240,241,242,243,244,245,246,247,248,249,250,251,252,253,254,255,256,257,258,259,260,261,262,263,264,265,266,267,268,269,270,271,272,273,274,275,276,277,278,279,280,281,282,283,284,285,286,287,288,289,290,291,292,293,294,295,296,297,298,299,300,301,302,303,304,305,306,307,308,309,310,311,312,313,314,315,316,317,318,319,320,321,322,323,324,325,326,327,328,329,330,331,332,333,334,335,336,337,338,339,340,341,342,343,344,345,346,347,348,349,350,351,352,353,354,355,356,357,358,359,360,361,362,363,364,365,366,367,368,369,370,371,372,373,374,375,376,377,378,379,380,381,382,383,384,385,386,387,388,389,390,391,392,393,394,395,396,397,398,399,400,401,402,403,404,405,406,407,408,409,410,411,412,413,414,415,416,417,418,419,420,421,422,423,424,425,426,427,428,429,430,431,432,433,434,435,436,437,438,439,440,441,442,443,444,445,446,447,448,449,450,451,452,453,454,455,456,457,458,459,460,461,462,463,464,465,466,467,468,469,470,471,472,473,474,475,476,477,478,479,480,481,482,483,484,485,486,487,488,489,490,491,492,493,494,495,496,497,498,499,500,501,502,503,504,505,506,507,508,509,510,511,512,513,514,515,516,517,518,519,520,521,522,523,524,525,526,527,528,529,530,531,532,533,534,535,536,537,538,539,540,541,542,543,544,545,546,547,548,549,550,551,552,553,554,555,556,557,558,559,560,561,562,563,564,565,566,567,568,569,570,571,572,573,574,575,576,577,578,579,580,581,582,583,584,585,586,587,588,589,590,591,592,593,594,595,596,597,598,599,600,601,602,603,604,605,606,607,608,609,610,611,612,613,614,615,616,617,618,619,620,621,622,623,624,625,626,627,628,629,630,631,632,633,634,635,636,637,638,639,640,641,642,643,644,645,646,647,648,649,650,651,652,653,654,655,656,657,658,659,660,661,662,663,664,665,666,667,668,669,670,671,672,673,674,675,676,677,678,679,680,681,682,683,684,685,686,687,688,689,690,691,692,693,694,695,696,697,698,699,700,701,702,703,704,705,706,707,708,709,710,711,712,713,714,715,716,717,718,719,720,721,722,723,724,725,726,727,728,729,730,731,732,733,734,735,736,737,738,739,740,741,742,743,744,745,746,747,748,749,750,751,752,753,754,755,756,757,758,759,760,761,762,763,764,765,766,767,768,769,770,771,772,773,774,775,776,777,778,779,780,781,782,783,784,785,786,787,788,789,790,791,792,793,794,795,796,797,798,799,800,801,802,803,804,805,806,807,808,809,810,811,812,813,814,815,816,817,818,819,820,821,822,823,824,825,826,827,828,829,830,831,832,833,834,835,836,837,838,839,840,841,842,843,844,845,846,847,848,849,850,851,852,853,854,855,856,857,858,859,860,861,862,863,864,865,866,867,868,869,870,871,872,873,874,875,876,877,878,879,880,881,882,883,884,885,886,887,888,889,890,891,892,893,894,895,896,897,898,899,900,901,902,903,904,905,906,907,908,909,910,911,912,913,914,915,916,917,918,919,920,921,922,923,924,925,926,927,928,929,930,931,932,933,934,935,936,937,938,939,940,941,942,943,944,945,946,947,948,949,950,951,952,953,954,955,956,957,958,959,960,961,962,963,964,965,966,967,968,969,970,971,972,973,974,975,976,977,978,979,980,981,982,983,984,985,986,987,988,989,990,991,992,993,994,995,996,997,998,999,1000-- -

Blue Team (Detection & Response)

Detection Steps:

1. Monitor HTTP POST requests to /chat/settyping.php for abnormal parameters.
2. Look for SQL keywords (UNION, SELECT, OR, AND, etc.) in request bodies.
3. Enable database query logging to detect anomalous SQL statements.

Response:

• Immediately block the IP address if an injection attempt is detected.
• Isolate the affected server and review database logs for data exfiltration.
• Apply virtual patching via WAF rules (see Detection Engineering).

Indicators of Compromise (IOCs)

Network IOCs:

• POST requests to /chat/settyping.php with parameters containing SQL keywords.
• Outbound database connections from the web server to unknown IPs.

File IOCs:

• Modified chat/settyping.php file (if attacker uploaded a webshell).
• Suspicious files in the chat/ directory.

Log IOCs:

• Database error logs containing SQL syntax errors.
• Web server access logs with UNION, SELECT, OR 1=1 patterns.

Remediation & Mitigation

Immediate Actions:

1. Disable Chat Feature: If not critical, disable the chat functionality by removing or renaming chat/settyping.php.
2. Input Validation: Implement strict input validation and parameterized queries for all database interactions.
3. Web Application Firewall (WAF): Deploy WAF rules to block SQL injection patterns (e.g., ModSecurity rule 942100).

Long-Term Fix:

• Upgrade to a patched version of Organizr once available.
• Conduct a full code audit of all PHP files for similar vulnerabilities.
• Implement a Content Security Policy (CSP) and use prepared statements universally.

Workaround:

• Use a reverse proxy (e.g., Nginx) to block requests to /chat/settyping.php with suspicious parameters.
